During gait analysis, the Achilles tendon is modeled as applying an upward force on the heel to produce plantarflexion about the ankle. The foot is approximated as a lever with the ankle as the pivot. The tendon inserts 5 cm behind the pivot, while the ground reaction force acts 15 cm in front of the pivot. Ignoring losses, which statement best illustrates mechanical advantage in this lever system?
