A construction worker of mass m, = 69.6 kg stands on a uniform ladder a distance d = 0.9 m from the bottom, measured along the ladder (Refer to the figure below). The ladder with mass m2 = 10.1 kg and length L = 3.8 m rests against a smooth wall. It makes an angle 31.3 degrees with the ground. There is a frictional force of magnitude f between the floor and the ladder. N, is the magnitude of the normal force exerted by the wall on the ladder, and N2 is the magnitude of the normal force exerted by the

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.
