g 2. The _ spans the distance from the _ to the location of the applied force. moment arm; pivot point moment of inertia; center of mass torque; center of mass None of the above

The moment arm seems to be the duration seen between joint as well as the force section trying to act mostly on the joint. Each joint that is already implicated in the workout seems to have a momentary arm.
The moment arm extends this same distance from either the pivot point to just the position of that same pressure exerted.
The pivotal point seems to be the technical indicators required to fully measure the appropriate demand trends alongside different time-frames.

The other three choices are not related to the given situation. So that option A is the appropriate choice.

g 2. The _____ spans the distance from the _____ to the location of the applied force. moment arm; pivot point moment of inertia; center of mass torque; center of mass None of the above
