Write your final answer in the specified area. Show your work step-by-step in chronological order with proper units. Attach additional sheets if required. No credit will be given to illegible work.

1. (10 pts) Solve for W (left hand) and U (right hand) in a linkage to carry the body shown below through positions P1 and P2 at the angles shown in the figure. Use analytical synthesis strategy #2 for your solution.

Given:Global Coordinate Frame Origin is P1Use the following free choices:WZ dyad: z = 1.5, 2 = 44.0 degrees, = -50.0 degreesUS dyad: s = 2.5, 2 = -55.0 degrees, = 20.0 degrees

Find [1 pt] 2 = __________ degrees[1 pt] 2 = __________ degrees[1 pt] |W| = ___________ in[1 pt] W1x = ___________ in[1 pt] W1y = ___________ in[1 pt] = ___________ degrees[1 pt] |U| = ___________ in[1 pt] U1x = ___________ in[1 pt] U1y = ___________ in[1 pt] = ___________ degrees
