Oscillations and Waves
3A - Oscillations
 |
3A 10.20 - Three Pendulums:
Demonstrates: Pendulum period is independent of mass. Description: Three pendulums, two of same arm length but different mass, one of same mass as one of the previous but with different arm length. |
 |
3A 10.30 - Torsional Pendulum:
Demonstrates: Torsional oscillation. Description: One cylindrical, one triangular with screw thread arms one on each face to adjust mass distribution. |
 |
3A 15.10 - Physical Pendulum:
Demonstrates: A different type of pendulum. Description: Two pendulums with non flexible arms. One with a meter stick as arm the other with steel rod as arm. Both with fixed masses. |
 |
3A 20.10 - Mass on a String:
Demonstrates: Simple harmonic motion. Description: Spring and various masses. |
 |
3A 40.10 - Harmonic Motion and Rotating Marker:
Demonstrates: Relationship between harmonic and oscillation motion. Description: Light source, mass on a spring, circular disk with paint cap. A specific oscillating mass for any given spring will appear to be in synch with the rotation of the disk. |
 |
3A 60.10 - Tacoma Narrows Video:
Demonstrates: Driven mechanical resonance. Description: Film of the Tacoma Narrows Bridge collapse. |
 |
3A 60.20 - Texas Tower:
Demonstrates: Resonance. Description: Variable oscillation driven mass and spring. |
 |
3A 70.10 - Wilburforce Pendulum:
Demonstrates: Simultaneous torsional and oscillational motion. Description: Cylindrical mass painted black and white and fixed to a spring. |
 |
3A 70.20 - Coupled Pendulum (large):
Demonstrates: Coupled harmonic motion. Description: Two side by side pendulums connected together by a spring at the mass ends. |
 |
3A 70.30 - Coupled Pendulum (small):
Demonstrates: Coupled harmonic motion. Description: Two side by side pendulums connected together by a spring at the mass ends. |
 |
3A 95.52 - Chaotic Pendulum (old model):
Demonstrates: Chaotic motion. Description: Two pendulums that are attached at the hip. |
