Question:

The leg is held in position by the quadriceps AB, which is attached to the pelvis at A. If the force exerted on this muscle by the pelvis is F, in the direction shown, determine the stabilizing g force component acting along the positive y axis and the supporting force component acting along the negative x axis.

Given:
F = 85 N
θ1 = 55 deg
θ2 = 45 deg

The leg is held in position by the quadriceps AB,
