Muscle Force Continued

To determine the muscle force needed to achieve a particular activity :

RECALL: Resultant force is equal to the sum of individual forces of a system.

In this example, the quadriceps muscles apply a force (Fmuscle) to the leg while the weight on the foot provides a resistant force (Fweight).

In order for the leg to move in the direction of Fmuscle, this force must be larger then that of Fweight.
