A disk having moment of inertia of 84 kg • m2 is free to rotate without friction, beginning from rest, around a fixed axis via its center. A tangential force whose magnitude can range from F = 0 to F = 50.0 N can be exerted at any distance ranging from R = 0 to R = 3.00 m from the axis of rotation.
(i) Determine a pair of values F and R which cause the disk to complete 2.90 rev in 10.3 s. (Assume that F = 31.0 N be one half of the pair.)
