The leg and cast in Figure P4.18 weigh 290 N, with the center of mass as indicated by the blue arrow in the diagram. The counterbalance w2 weighs 125 N. Determine the weight w1 and the angle α needed in order that there be no force exerted on the hip joint by the leg plus cast.

except in my picture the boxes are labeled differently (pretend w1 is actually w2 and the same with the other box, thanks)
