an 8kg flywheel of radius r is
initially at rest. assume the radius of the gyration kG= 0.12m and
the radius of the flywheel r = 0.125m. an object B also of mass 8
kg is attached to a cord that is wrapped around a periphery of the
flywheel. the fly wheel starts to rotate clockwise with angular
velocity. the rotation is resisted by a constant frictional torque
mf in the bearing 1Nm. use the work energy principle to determine...
Suppose you exert a force of 190 N tangential to the outer edge
of a 1.585-m radius 75.5-kg grindstone (which is a solid disk).
a. What is the torque τ, in newton meters, you are
exerting on the grindstone, relative to the center of mass of the
grindstone? (I believe the answer is
301.15)

α0, in radians per square second, assuming
negligible friction?

Please answer part B. (3.16 is NOT the correct answer)
An object of mass M = 5.00 kg is attached to a spring with spring constant k = 55.0 N/m whose unstretched length is L = 0.180 m, and whose far end is fixed to a shaft that is rotating with an angular speed of omega = 1.00 radians/s. Neglect gravity and assume that the mass also rotates with an angular speed of 1.00 radians/s as shown....
