In the figure, a uniform plank, with a length L of 4.75 m and a weight of 630 N, rests on the ground and against a frictionless roller at the top of a wall of height h = 2.36 m. The plank remains in equilibrium for any value of 0 = 70.0° or more, but slips if < 70.0°. Find the coefficient of static friction between the plank and the ground. Roller 1. h

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.
