WebA young biomechanist, Ted, is attempting to estimate a muscle's active force-length curve. However, he cannot isolate the muscle of interest, but instead can only perform experiments on the muscle-tendon actuator as whole. He performs a series of trials where the musculotendon actuator is held isometric and tendon force is measured in steady state.
