The cylinder of weight, W, shown below is being hoisted up with the force F against the vertical wall. If us = 0.57 a. Determine the reaction force (resultant of normal force and frictional force) against the vertical wall. b. Calculate the force, F, needed to set the cylindrical roller in motion W or W1 (in kN) = 516
