The
illustration shows a diagram of a person standing on the right lower extremity.
The right hip abductor muscles must contract to counteract the force of
gravity and keep the pelvis level. How much force must the right hip abductor
muscles generate to keep the pelvis level? Given information is: Body weight
= 150 lb., AB = 2", BC = 4", angle BAM = 70 degrees. Solve for the magnitude
of M.
