1) Consider the figure below. The inside radius is 0.25 m and the outside radius is 0.4m.
a) What for F is needed to put the disk in rotational equilibrium (assume there is an axle at the center of the disk – it can
only spin if the right forces/torques are applied -it can't move sideways).
b) Suppose the mass of the disk (though it has an inside/outside radius, treat it as a solid disk with the outside radius) is 8 kg,
and the force F is only half of your answer in A... calculate the angular acceleration of the disk (and which way it rotates).
c) Suppose the force F were twice what your answer was in A- calculate the angular acceleration.
d) in Part C, if you started the disk from rest, with that angular acceleration – calculate how much time (seconds) it would
take to rotate exactly 10 times?
