Torque Ladder Example Solution

This is the video solution to a problem when a ladder rests on a wall. Its solution involves the 1 conditions of static equilibrium by looking the sum of the forces in perpendicular directions and the sum of the torques about any pivot point. Here's the question, "A 5 m, 200N, long ladder rests on a wall. The ladder's center of mass is 3 m from the bottom along the ladder. There is no friction on the wall, but there a coefficient of friction along the ground of 0.300. How far along the ladder can a 750 N person climb above the ground?"
