PROBLEM 1. A wedge assembly, composed of wedges X and Y, is designed to lift crate W whose weight is 1CDE N, as shown in the figure below. What will be the maximum force P that can be applied before movement begins if the coefficient of friction for all surfaces of contact is 0.0875? Draw all necessary free-body diagrams and indicate the direction of impending motion. GIVEN: 1CO = 160 1D = 140 1E. = 180 1CDE N = 1648 N
