71Relatively an easy one. (Compared to the degree of questions you solve :P )
Block C has a mass of 50 kg and is confined between two walls by smooth rollers. If the block rests on top of the 40 kg spool, determine the minimum cable force P needed to move the spool. The cable is wrapped around the spool's inner core . The coefficients of static friction at A and B are 0.3 and 0.6 resp.
I'm getting the answer as 705.6N
Please solve.
