A uniform ladder weighing 100N leans against a smooth vertical wall with its lower end resting on a rough floor, the ladder making an angle of 70o with the horizontal. Find (a) the force exerted by the wall on the ladder and (b) the force exerted by the floor at the lower end of the ladder.
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.
