A 10 m long and 20 kg ladder leaned against a vertical wall at an angle of 53o to the horizontal. The friction coefficient between the stairs and the ground is 0.3. The ladder does not rub against the wall. The first step of the ladder (the distance from the end of the ladder to the first rung) and the other steps are 37 cm. dir. How many steps can a man with a mass of 70 kg climb without slipping? (g = 10 m / s2, cos53o = 0.6, sin53o = 0.8)

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.
