2. As a person is running, their soleus, gastrocnemius and tibialis anterior muscles generate forces about their ankle joint. During late stance, the magnitudes of the forces are soleus 1550 N and tibialis anterior 825 N. The magnitudes of the muscle moment arms about the ankle joint are soleus 0.06 m, gastrocnemius 0.07 m, and tibialis anterior 0.04 m. What is the force generated by the gastrocnemius muscle if the net torque is -150 N m (negative - plantarflexion)? What is the force generated by the gastrocnemius if the net torque is -75 Nm (negative plantarflexion)? Gastrocnemius muscle force at net torque of -150 N m Gastrocnemius muscle force at net torque of -75 N m I

As a person is running, their soleus, gastrocnemius and tibialis anterior muscles generate forces
about their ankle joint. During late stance, the magnitudes of the forces are soleus 1550 N and tibialis
anterior 825 N. The magnitudes of the muscle moment arms about the ankle joint are soleus 0.06 m,
gastrocnemius 0.07 m, and tibialis anterior 0.04 m. What is the force generated by the gastrocnemius muscle
if the net torque is -150 Nm (negative = plantarflexion)? What is the force generated by the gastrocnemius if
the net torque is -75 Nm (negative plantarflexion)?
