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 motion. e Law necessary free-body diagrams and indicate the direction of impending

The mechanism used in a marine engine consists of a single crank AB and two connecting rods BC and BD as shown in (Figure 1). Assume r = 0.2 m Part A Determine the magnitude of the velocity of the piston at D the instant the crank is in the position shown and has an angular velocity of w 4 rad/s.
