The wheel is hung from a rope while it is spinning and it precesses. Use the bicycle wheel and rotating platform to demonstrate conservation of angular momentum. Location: To the right of Shelf Q")
• 12:20, 6 April 2022 Physdemo talk contribs created page Rotating Candles (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Rotating_Candles.gif}} The candles are inside glass tubes. As the apparatus spins, the flame of the candles point towards the center of rotation where the density of the air has decreased. '''Location: ''' * Drawer 16")

Wind the strings up on the axle (with each turn to the inside of the previous) and let go. When it reaches the bottom it will climb nearly as high as its beginning point. Be sure that the strings are of equal length to ensure proper operation. Also check that they wind towards the center to keep the strings...")
• 12:19, 6 April 2022 Physdemo talk contribs created page Gyroscope, Air (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Gyroscope-Air.gif}} A heavy gyroscope which uses pressurized air for a nearly frictionless bearing. '''Location:''' *Sh. H-2")

• 12:18, 6 April 2022 Physdemo talk contribs created page Inertia Wheel (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Inertia_Wheel.gif}} This is an aluminum disk with two diameters which is free to rotate. The moment on inertia remains constant but it is possible to exert two different torques with a single mass. Set this at the edge of a table, roll a string around one of the diameters and attach a mass. The rate of fall is significantly different for the two diameters. '''Location:''' * Sh. B-3")
• 12:17, 6 April 2022 Physdemo talk contribs created page Angular vs. Linear Momentum (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Angular_vs_Linear_Mo.gif}} A pin connects the large wheel to the shaft. With the pin removed, only the shaft turns as the assembly moves down the ramp. With the pin in place, the large wheel rotates with the shaft. This absorbs much of the energy of the system and causes the assembly to move down the ramp at a much slower rate. '''Location: ''' * Sh. B-2")
• 12:17, 6 April 2022 Physdemo talk contribs created page Water in the Bucket (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Water_In_The_Bucket.gif}} The classic spinning bucket with water in it. Ours is a clear bucket to allow observation of the water while spinning.< '''Location:''' * Sh. B-3")
• 12:15, 6 April 2022 Physdemo talk contribs created page Inertia "M" (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Inertia_M.gif}} A wire is bent in the shape of an M. 100g masses, one silver one black, are placed on the ends of the wire. The center of the M is balanced on your head with one of the masses directly in front of your face. Rotate your body and you can look at the other mass. The M will not rotate with you because it has Rotational Inertia. '''Location:''' * M - Shelf B2 * Masses - Shelf A4")

The technique should be practiced before using in class. '''Location: ''' * SH. E-0")
• 12:10, 6 April 2022 Physdemo talk contribs created page Centripetal Force 1 (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Centripetal_Force-1.gif}} Spinning of the central assembly will cause the bob to swing outward, this force being countered by the spring. Use the pointer to locate the radius of the motion. By then attaching masses to the stationary bob to bring it back over the pointer, the centripetal force can be calculated. '''Location:''' * Sh. O-1")
• 12:09, 6 April 2022 Physdemo talk contribs created page Mystery Wands (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Mystery_Wands.gif}} This is a matching set of aluminum tubes of equal mass. However, one has it's internal weights located near the center while the other has them at the ends. They can be spun together about a small rod or in the hands to show that they have different movements of inertia. '''Location:''' * Sh. B-2")
• 12:09, 6 April 2022 Physdemo talk contribs created page Torque Bar (Created page with "{{NewDemo|subject=Mechanics|topic=Rotational Dynamics|file1=Torque_Bar.gif}} A way to give students a hands on understanding of the lever arm. Most everyone can pick up two kilos in the hole nearest the handles. Few can do so at the furthest end. Caution: Those who try too hard to hold up the heavy mass at the far end may find that while their grip may hold their skin may not. Prep room staff have received very nasty blisters from this.

They are set rolling together but the solid one will move ahead demonstrating its lower moment of inertia. '''Location:''' * Cylinders: Dr. 9 * Ramp: Next to Sh. A")

• 11:24, 6 April 2022 Physdemo talk contribs created page Impulse Pendulum (Created page with "{{NewDemo|subject=Mechanics|topic=Impulse and Linear Momentum|file1=Impulse_Pendulum_better.jpeg}} Everyone is probably familiar with the Happy/Sad Balls or the Bounce No Bounce balls available from toy stores or Arbor Scientific. Once I bought a set that included one ball where one side bounced and the other did not; two half balls glued together. I used this half happy ball to demonstrate the different impulses delivered by a bouncing ball and a ball that does not bou...")
