**Educational Content: Understanding Torque and Force in the Human Leg** ### Diagram Explanation The diagram shows the anatomy of a human leg highlighting the application of torque. It illustrates a bent leg with the lower leg raised, showing: - **Tendon Function**: The tendon provides the torque needed to raise the lower leg. - **Dimensions**: - The length from the knee joint to the ankle is marked as 50 cm. - The perpendicular distance from the tendon attachment to the knee joint is marked as 5.0 cm. ### Problem Description To explore the concept of torque and balance, we examine a scenario where an individual stands on one foot while holding the other leg in a raised position. In this position, the muscles must exert a force to maintain the leg's position. #### Assumptions: - The lower leg and foot together have a combined mass of 3.2 kg. - The center of gravity is at the center of the lower leg. - Use a gravitational acceleration value of \( g = 10 \, \text{m/s}^2 \). ### Question Calculate the force (in Newtons) that the tendon must exert to maintain the leg's position in this scenario. Provide only the numeric force value as your response. This exercise illustrates the application of physics concepts such as torque, forces, and the role of tendons in human movement.
