A mass m hangs on the end of a cord around a pulley of radius a
and moment of inertia I, rotating
with an angular velocity w, as shown in the figure below. The rim
of the pulley is attached to a
spring (with constant k). Assume small oscillations so that the
spring remains essentially
horizontal and neglect friction so that the conservation of energy
of the system yields:
1/2mv^2 +1/2Iw^2+1/2kx^2-mgx=C,
where w=v/a, C=const, x+displacement from equilibrium

The left-hand end of a long horizontal stretched cord oscillates transversely in SHM with frequency 270 Hz and amplitude 2.6 cm . The cord is under a tension of 100 N and has a linear density 0.07 kg/m . At t=0, the end of the cord has an upward displacement of 1.8 cm and is falling. Consider the point x = 0.500 m on the cord. Part A Determine the maximum velocity of this point. Part B Determine its maximum...

A solenoid passes through the x-y plane. A charge of +9 Coulombs with a mass of 3 x 10-7 kg moving at 9 m/s (in the x-y plane) is placed in the solenoid. Due to the magnetic field produced by the solenoid, the charge moves counter-clockwise in a circle at a frequency of 28 Hz. The charge is removed and a circular wire wound 2 times with a radius of 0.6 meters is placed in the solenoid. If the total...
