Question: Problem 4 : The hook wrench or pin spanner is used to turn shafts and collars. The 2 0 0 mm diameter shaft is supported

Problem 4:
The hook wrench or pin spanner is used to turn shafts and collars. The 200 mm diameter shaft is supported by a set of bearings along its axis O . A brake on the shaft prevents it from turning. It will take a moment of 80N-m to just overcome the braking force and allow the shaft to begin to rotate cw. What is the required force P to just break the shaft free (i.e. impending motion)? Also determine the normal contact force on the smooth surface at A. Engagement of the pin at B may be considered to occur at the periphery of the collar. The pin interface at B can support both a tangential and normal load. Assume massless parts and zero friction except for the brake. You must draw a separate FBDs of the spanner and cylinder!
