Question

Question 22 of 30> The femur of a human leg (mass 10 kg, length 0.9 m) 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 masses mi and m2, 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 mi to m2 in terms of m2 and numerical coefficients. Is the expression for my valid for more than one pair of values of mi and m2? Oyes O no Suppose the tension force due to mi is now applied at the leg's center of mass. Write a new expression relating mi to m2 in terms of m2. numerical coefficients, and given values. If you use a given Write a mathematical relationship relating mi to m2 in terms of m2 and numerical coefficients. rnl = Is the expression for mi valid for more than one pair of values of mi and m2? O yes O no Suppose the tension force due to m is now applied at the leg's center of mass. Write a new expression relating m 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.
