01Why does moving a weight farther away feel harder?Axis, distance and external moment02Does force direction change torque?Angles, levers and mechanical advantage03Why can muscle force exceed the load?Rotational equilibrium and joint reactionKeep this question in mind
Before calculating: Which joint? Which axis? Which force? Which perpendicular moment arm?

These notes explain a simplified model of mechanics. They do not estimate a specific patient’s internal forces or replace supervised laboratory learning.
