Spin Art... centripetal force..."centrifugal" force // Homemade Science with Bruce Yeany
 
10:51
Spin art has been a popular device in the arts and science over the years. It is rather simple, spin a piece of paper at high speeds, splash some paints on it and then stop it and admire the results. It can be a nice piece to start a discussion on the application of centripetal forces, "centrifugal" forces, inertia, color mixing or simply a fun activity for children of all ages.

Spin art, simple homemade device /////Homemade Science with Bruce yeany
 
03:45
This simple device has seen a lot of use and is very popular with students. We use it as an example when exploring the concept of centrifugal force. There are several good demonstrations showing this concept, however,this centrifugal force can be misleading since it is not a real force. It is suggested that a good lesson accompany the use of these devices, otherwise students may end up with misconceptions of what is observed. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations. Videos are shot with a Casio EXH20. Slow motion shots are either 3.5 or 7 times slower.

Thanks for watching! I actually had an early version of this ready last week. Which you can watch here on my second channel: https://www.youtube.com/watch?v=x9B0xCm87xI I decided, with the help of my Patreon supporters, that it wasn't good enough. Have a few ideas for my next video. Space X is winning right now. What do you think? I may try to work on two videos at once this week. Woops forgot the math: The equation is a=(w^2)*r where a is the acceleration, w is the angular velocity and r is the radius. First we must convert RPM to radians per second. There is 2(pi) radians per revolution and 60 seconds in a minute. So one RPM equals 2(pi)/60. We then simply enter these values into the equation. For our first calculation on space station v we get a=(0.1047)^2*150=1.65 ms^-2 Patreon: https://www.patreon.com/user?u=2825050&ty=h Facebook: http://facebook.com/realengineering1 Instagram: https://www.instagram.com/brianjamesmcmanus Twitter: https://twitter.com/Fiosracht Once again thanks to Bensound.com for the amazing royalty free music.

This video does not include the building of the machine as that is video #3. Accoding to KIDDLE (The Kids Encyclopedia) In physics, centrifugal force (from Latin centrum "center" and fugere "to flee") is a fictitious force that appears when describing physics in a rotating reference frame; it acts on anything with mass considered in such a frame. Centrifugal force is fictitious because although it may feel to a person like a certain force is being exerted on them, someone outside the scene will see something different. Example: If John is in a car that takes a sharp right turn, he will feel as though he is being pushed to his left. This is an imaginary force, called a centrifugal force, or a "running away from the center" force. John feels it because he is inside the car and is affected by it. However, if John's friend, Andy, is on the side of the road facing the front of John's car and watches John's car take a sharp right turn, Andy will see the car push John to the right with the car as it changes direction. This is a real force called centripetal force (or an "aiming towards the center" force) and acts towards the center of the circle of rotation. In other words, John's body, traveling in a straight line before the car turned, wanted to keep moving in a straight line because it had momentum in that direction, but the car, which was exerting a force on John by turning, is pulling him to the right. John feels like his body is being pushed to the left as the car turns, but in fact, his body is being pulled to the right by the turning car. This is a problem that appears in rotating situations. There is a difference between what appears to be happening if watched from the outside or if the event was seen from within a rotating object. These differing viewpoints are called frames of reference. Despite the name, fictitious forces are experienced as very real by anyone whose immediate environment is a non-inertial frame. Even for observers in an inertial frame, fictitious forces provide a natural way to discuss dynamics within rotating environments such as planets, centrifuges, carousels, turning cars, and spinning buckets.

Toy Physics - Looping Pendulum /// Homemade Science with Bruce Yeany
 
04:00
This is a simple demonstration that can be used to impress your friends using a variety of materials. It also can make a nice investigation for a science fair project or a classroom demonstration. Students can test variables and determine the conditions for the best results. The use of small lights and a camera can help capture the beauty in the movement of the small weight as it arrests the movement of the larger weight as it falls. Or, one other use can be for amusement purposes by turning the demonstration into a game. One final note, the spiral path recorded in the pictures was described as an Archimedes spiral, it is actually an involute spiral. While they are very similar, there are subtile differences that can be explained and demonstrated by searching for definitions of these terms. Sorry for the mistake.

Centrifugal tray////Homemade science with Bruce Yeany

The classic demonstration of swinging a bucket over your head is taken up on notch by swinging a cup of water on a tray. Swing vertically or horizontally or a combination of both and the water remains in the cup to the "centrifugal force" acting on the cup. WHile this and other experiments demonstrating centrifugal force are a lot of fun, the concept can be misleading . A good lesson should accompany centrifugal force demonstrations to help clear up any misconceptions.

Paper Saw Blades- paper cuts paper- Part 1- centrifugal force  //  Homemade Science with Bruce Yeany
 
06:47
Part one: Can a saw blade made out paper cut through a sheet paper? It can if it's spinning fast enough. Circles of paper are mounted onto a Dremel type tool and then are tested to see if they can cut paper, cardboard foam cups, even thin strips of wood. However, don't look to replace your steel saw blades with these anytime soon, these will disintegrate after a few uses, after all, they are just paper. The demonstration relies on the concept referred to as "centrifugal force". I would point out that this is a fictitious force. The behavior that it describes is real enough, however the words defining it are incorrect. the term "force" used with the word centrifugal is misleading and wrong, there is no force applied radially outwards. However, even though it is mislabeled, the term centrifugal force is used to describe the motion of the matter or an object moving radially outwards. This is what we observe here when the paper straightens out when spinning or the string on a grass trimmer becomes rigid as it spins and can be seen in all sorts of other examples and applications all well. It can be as simple as soaking a towel with water and spinning it over your head. The water drops move away from the towel outwards from the center of rotation ( centrifugal force). We can actually see similar results in the paint trails in the pictures at the endo of my spin art video. https://www.youtube.com/watch?v=FF0U7YIwm4M My preference would be to call it a centrifugal behavior. What we are seeing is a cause and effect. The centripetal force which causes the object to curve off of a straight is applied inwards towards the center of rotation. This inward force pulls against the inertia of the object and the effect or result is an outward movement even though there is no outward force. One further note on safety: I recognize that using the table saw without the guard down is dangerous, it was left up for visual purposes of making the video. My standard procedure is normally to use all safety measures available when using power tools. Also, as has been suggested, I would very strongly recommend that anyone attempting this experiment wear gloves as protection against paper cuts.

Angle of repose…Physics of toys  //  Homemade Science with Bruce Yeany
 
04:47
The angle of repose or critical angle of repose is how steep various types of materials can be piled without slumping. The steepness of the side of a pile is determined by the amount of friction between the particles of matter. This can vary according to size and density of the material, particles size, smoothness of the particles, whether it is wet or dry, and any cohesive properties of the matter. Materials such as sand piles, dirt, sugar, flour, stones and every other type of loose matter will all exhibit this property. Here are a couple of devices that were made for demonstrating this process using sand without it making a mess.

Triple fun with straw | Kannada
 
02:22
You can play with this wonderful 3-in toy and make it with a single plastic straw and a piece of rubber. Take a plastic straw and cut it in two roughly equal parts. Take one piece and make two triangular cuts making triangular reeds. When we blow with these reeds in mouth, these reeds will vibrate and the straw will make a straw flute. Press the reeds a little flat to make the flute work. Now take the rubber piece and apply glue on two sides and stick the two straw pieces. Be careful to push the flute straw over the edge to cover the other straw halfway. This ensures the blocked straw piece works like a mist. And now you are ready to have fun. Because the straw blocks the air flow, the speed of air increases over the straw and creates a low pressure (Bernoulli’s principle). This lifts the water in the straw and you can see. The rising water gets converted to fine mist spray. If you insert a wooden in the rubber piece this becomes a sprinkler. You can see here how the sprinkler works. Put two beads in two straws and one in the central wooden stick. Now when you spin the beads in the straw fly away, just like the water droplets in the sprinkler, due to centrifugal force. The bead in the center however stays no matter how hard you spin because the centrifugal force at the axis is 0. So enjoy the 3 in straw fun with flute, spray and sprinkler.

The basic concept of a reciprocating engine goes back about 300 years when first developed into a crude stream engine. the same basic principles are used in today's modern engine where expanding gas is used to drive a piston and a crank is used to convert the movement into rotary motion. This engine will run on the either the exhaust or vacuum of a shop vac, a vacuum sweeper, or compressed air. The stroke of the piston is 4 inches The movement of the cam to drive the air diverter is 2 inches 240 RPMs as shown... max is about 400 RPMs

The front fork off of a bicycle makes a nice addition to a tuning fork set. The frequency of this one is very low, about 54 Hz (vibrations per second). The sound of fork is very deep and the camera does not do a good job of picking it up but otherwise, it makes for an interesting piece of equipment. My students have found it to be entertaining to hold it against various surfaces, and in doing so it can be heard in other classrooms adjacent to mine.

Chladni plates & mechanical driver- cheap! //  Homemade Science with Bruce Yeany
 
05:55
The use of Chladni plates can make a wonderful demonstration but can be rather expensive for equipment that may have limited use in the average classroom. This video shows how I set up the experiment using a free online tone generator on my computer, a discarded amplifier, a mechanical driver easily made from an old discarded speaker and some plates that were cut out of sheet metal. This video was made with very little practice, the plates were quickly cut and not squared or with the hole not being exactly centered. I'll be experimenting with other materials and shapes to see what additional patterns can be formed. For now, this is a good start to my investigation.

Here is a reexamination of the fan cart and the popular demonstration of what would happen if you try to blow into your own sail. The misapplication of Newton's 3rd law as used in a children’s storybook and why it is wrong are shown along with some other variation suggested by viewers are tested in this latest video on the fan cart. I have intentionally tried to keep it’s explanation in simple terms for younger students since there are several higher level explanations already available from a variety of sources on the internet and here on youtube. Note on comments: I appreciate seeing comments positive or negative, and learn from helpful criticism. However, I am a middle school teacher and many of my students visit this site, I will remove comments that I feel are offensive or inappropriate.

Magnetic Spin Current Flows in the Human Psyche
 
07:37
This audio-video illustrates one more of my many 2D drawings of theories related to human magnetism with the specific aim of mapping or modeling magnetic spin current flows. The purpose is to show a number of ways to conceptualize and to visualize how magnetism may shape, form or pattern the human psyche. I have attempted to look at these questions from every possible angle or perspective. As I have worked on these ideas and made a variety of drawings, some features of this theoretical model have become more clear as the correlations between this picture of the human being and many known facts have become apparent. I am relatively certain that this model of the human psyche can explain the real forces shaping the human being. The questions now are: How does it work? How do we map it? How do we model it? How do we test it scientifically? What this particular drawing shows is three magnetic centers in the human psyche located in the Navel, in the Solar Plexus and in the Head. The forms of the two brain hemispheres, the two lungs, as well as the pelvis and buttocks suggest 6 distinct magnet spin forces in the human psyche that are primary. Any other magnetic spin forces are secondary. What can also be seen are two primary magnetic current flows that cross the physical body: the first magnetic current flow follows the pathway from the right side of the head, along the right side of the chest and through the left side of the pelvis down to the left leg; the second magnetic current flow follows the pathway from the left side of the head and chest and through the right side of the pelvis and down the right leg. With these primary magnetic spins I may have chosen one or the other of the spin directions incorrectly but the principle still holds. It seems that each of the primary magnetic spins in the human psyche spin outward from the centerline of the human body in either a clockwise or an anti-clockwise direction. The two brain hemispheres, the two lungs and the two buttocks may provide clues as to the direction of the magnetic spins that shape them. Likewise, the North and South magnetic current flows cross alternately from the left side to the right side of the body and back again. Whether or not my depiction of this process is precise or is inaccurate is immaterial. These principles will hold true regardless of how imprecise this drawing is! The navel and solar plexus region can clearly be seen to be a resorvoir for energies, possibly some magnetic, some electrical, some photonic and maybe even gases and plasma's as well. The legs "spin out" from the two magnetic spins in the pelvis region combined and the arms "spin out" from the combined magnetic spin forces of the head and the chest. These facts may explain the differences between the form and structure of the legs relative to the arms. There are probably many other insights to be gleaned from this model that I have not noticed of considered. Thanks, G.
