- A 200 Lb Block Is Suspended From An Inextensible Cable Which Is Wrapped Around A Drum Of 1 3 Ft Radius Rigidly Attached 1 (14.05 KiB) Viewed 42 times
A 200 lb block is suspended from an inextensible cable which is wrapped around a drum of 1.3.ft radius rigidly attached to a flywheel The drum and flywheet have a combined centroidal moment of Inertial =10 lb-ft-s? At the instant shown, the velocity of the block is 5 ft's directed downward. Knowing that the bearing at Ais poorly lubricated and that the bearing friction is equivalent to a couple M of magnitude 60 lb-ft determine the work or U1-2 linft-Ib) after it has moved 4.2 ft downward. 200
