20.2.14
A pair of forces is applied to cylinder 1 with a moment M = 120 N • m and a moment of friction forces Mtr
= 10 N • m. At the end of the inextensible thread, a load of 2 masses m2 = 40 kg is attached. Choosing as
Generalized coordinate angle? Determine the generalized force if the radius R = 0.3 m. (Answer -7.72)
