Chapter 9, Problem 67GP

& Bio Leg lift You are doing one-leg leg lifts (Figure P9.67) and decide to estimate the force that your iliopsoas muscle exerts on your upper leg bone (the femur) when being lifted (the lifting involves a variety of muscles). The mass of your entire leg is 15 kg. its center of mass is 0.45 m from the hip joint, and its rotational inertia s $\text{4}\text{.0**\#x00A0;kg }\cdot {\text{ m}}^{\text{2}}$, and you estimate that the rotational acceleration of the leg being lifted is ${\text{35 rad/s}}^{\text{2}}$. For calculation purposes assume that the iliopsoas attaches to the femur 0.10 m from the hip joint Also assume that the femur is oriented 15^* above the horizontal and that the muscle is horizontal. Estimate the force that the muscle exerts on the femur.
