The femur of a human leg (mass10kg,length0.9m) is in traction, as shown in the figure. The center of gravity of the leg is one-third of the distance from the pelvis to the bottom of the foot. Two objects, with masses1and2,are hung at the ends of the leg using pulleys to provide upward support. A third object of8kgis hung to provide tension along the leg. The body provides tension aswell.

Make a mathematical relationship relating1to2in terms of2and numericalcoefficients.
