FA 4.0 cm Fp -12 cm- N=-W A 75-kg man stands on his toes by exerting an upward force through the Achilles tendon. The fulcrum is shown with a blue triangle (disregard the black fulcrum at the ankle). FA is the effort force, and Fp is the load force from the body. (a) Label the lever system presented in the image. (b) Calculate for mechanical advantage. (c) Is this system at a mechanical advantage or disadvantage? (d) What is the length of the moment arm related to the Achilles force vector (from the fulcrum at the forefoot)? (e) What is the torque created by the Achilles Tendon in relation to the fulcrum point? The force in the Achilles tendon is (FA)=20N FA 4.0 cm Fp -12 cm- N=-W A 75-kg man stands on his toes by exerting an upward force through the Achilles tendon.
