1.The wedge is used to level the member. Determine the horizontal force P that must be applied to move the wedge to the right. The coefficient of static friction between the wedgeand the two surfaces of contact is ?s=.25. Neglect the size and weight of the wedge.
2.Compute the energy loss in a 90 degree bend in a steel tube used for a fluid power system. The tube has a 0.5 inch outside diameter and a wall thickness of 0.065 inches. The mean bend radius is 2.00 in. The flow rate of hydraulic oil is 3.5 gal/min.
