PHYS 7010-001: Theoretical Mechanics

• a short length of chain

• Soap Films
  (Pyrex dish with two large circle frames )

• brachistochrone curve apparatus made of brass wire, a disc with dot on rim to illustrate a cycloid generated by a rolling circle

• large wood ball pendulum with < 1cm diameter ring to slide down string to show pendulum period gets shorter

• Coupled Pendulum Oscillators

•  video  - Inverted Pendulum - Function Generator
  (let pendulum hang downward, give it a nudge, its natural frequency is about 2.6Hz, now drive rod at about 5.2Hz, pendulum frequency measures 318rpm w/ laser tachometer, which you divide by 2 (pendulum breaks beam twice during one period) to give 2.65Hz)

•  video  - Inverted Pendulum - Function Generator
  (inverted mode & horizontal mode)

• two copper sticks soldered together in the center at 45-degrees, with styrofoam balls on either end of one of them, a regular sized football

• football & cone with point to roll around

• football

• Air Gyro
  (with red compressed air tank and compact regulator on cart)

• Ball rolling on a rotating table - flat and tilted cases w/ 1-inch steel ball

• Ball rolling inside a cylinder - use racket ball in plastic "bell jar" and get it spinning by doing a "hula-hoop" motion with the jar - http://www2.eng.cam.ac.uk/~hemh/movies.htm

• 4 coffee filters
