A 5.0-m long, 15-kg uniform ladder rests against a smooth vertical wall with the bottom of the ladder 3.0 meters from the wall. The coefficient of static friction between the floor and the ladder is 0.28. What distance (d), measured along the ladder from the bottom, can a 60.0 kg person climb before the ladder starts to slip? Hint: the center of gravity of the latter is at its geometry center. Show all work including but not limited to coordinate system, equations along the axis, free body diagrams and torque diagrams. u = 0.28

Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics. 

Equilibrium of Forces

The tension created on one body during push or pull is known as force.
