Question

The femur of a human leg (mass 10 kg, length 0.9 m ) is in traction.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 masses m 1 and m 2 , are hung at the ends of the leg using pulleys to provide upward support. A third object of 8 kg is hung to provide tension along the leg. The body provides tension as well. Write a mathematical relationship relating m 1 to m 2 in terms of m 2 and numerical coefficients.

I know that m₁=2m₂

Is the expression for m1m1 valid for more than one pair of values of m1m1 and m2?

The answer is no

but what is the answer for this part:

Suppose the tension force due to m₁ is now applied at the leg's center of mass.

Write a new expression relating m₁ to m₂ in terms of m₂, numerical coefficients, and given values. If you use a given value in your equation, enter it as a number without units.

m₁₌?????
