Answer A & B оn yоur pаper exаm. A pаtient is perfоrming a straight leg raise (hip flexion). The leg is elevated 20 degrees from the floor. The weight of the lower extremity is 120 N and the center of mass is located 30 cm from the hip joint axis. The illiopsoas inserts at an angle of 10 degrees at a distance of 5 cm from the hip joint axis of rotation. Consider the lower extremity as a rigid body, the free body diagram is given below. To set up the calculation using variable names as given in the free body diagram, write the equilibrium equations necessary to solve this problem (but do not solve yet) for unknown muscle torque, and overall muscle force. Account for the proper sign of the forces and torques, if a force or torque is zero, either do not include it in the equation or make it clear that it is 0. Draw the coordinate system you will use to solve this static equilibrium problem, including the positive torque direction:
