, the muscle is activated to a
specified predetermined level, and the
tendon force is measured
after once the muscle and tendon
reach have reached equilibrium (
steady statei.e., muscle and tendon forces are equal). The muscle has the following
active and passive force–length relationships:
...
For each of the following experimental conditions , calculate (specified activation and measured tendon force), calculate the length of the muscle
