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.

no friction # Will the ladder slip? A ladder of length l = 4m rests against a wall at 0 = 60°. ASsume that there is no friction between the ladder and (A ladder the vertical wall but there is friction between the ground and the ladder with u = 0.5. A person weighing 700 N starts to climb up the ladder. 1. Can the person make it to the top safely (without the ladder slipping)? If not, then find the distance d along the ladder that the person can climb safely. Ignore the weight of the ladder in comparison to the weight of the person. 2. Does the "no slip" distance d depend on 0? If yes, then find the angle 0 which makes it safe for the person to reach the top. W friction B
