A horizontal force F is applied to the ladder at distance d = 1.6 m from its base (measured along the ladder). If force magnitude F = 58 N, what are (a)x-, (b)y-components of the force of the ground on the ladder? If F = 140 N, what are (c)x-, (d)y- components of the force of the ground on 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.

Question

A uniform ladder is 15 m long and weighs 210 N. In the figure, the ladder leans against a vertical, frictionless wall at height h = 6.5 m
above the ground. A horizontal force F is applied to the ladder at distance d = 1.6 m from its base (measured along the ladder). If force
magnitude F = 58 N, what are (a)x-, (b)y-components of the force of the ground on the ladder? If F = 140 N, what are (c)x-, (d)y-
components of the force of the ground on the ladder? (e) Suppose the coefficient of static friction between the ladder and the ground is
0.38; for what minimum value of the force magnitude F will the base of the ladder just barely start to move toward the wall?

A painter wishes to know whether or not he can safely stand on a ladder. The ladder has a mass M1 = 10 kg which is uniformly distributed throughout its length L = 7.1 m.

If the painter does not stand on the ladder, what is the minimum angle theta for which the ladder will remain stable?
