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.

A 10.0-kg monkey climbs a uniform ladder with weight w = 1.09 ✕ 102 N and length L = 3.40 m as shown in the figure below. The ladder rests against the wall at an angle of ? = 60°. The upper and lower ends of the ladder rest on frictionless surfaces, with the lower end fastened to the wall by a horizontal rope that is frayed and that, can support a maximum tension of only 80.0 N.
A 30 ft ladder, weighing 100 lbs having its center of mass one-third of the way up from the bottom, rests against a smooth wall so that it makes an angle of 60° with the ground.

The upper end of a wide-skid W 8 × 21 steel column (E = 30 × 103 ksi) is supported laterally between two tubes (see figure). The tubes are not attached to the column and the friction between the tubes and the column is not reliable. The base of the column provides fixed support and the column is 13 ft long. Determine the critical load for the column, consider the Euler buckling in the web plane and also perpendicular to the web plane.

The ladder has 7 rungs and the rungs are spaced 0.30 m apart, and the top and bottom rungs are 0.30 m from their respective ends of the ladder. Surfaces at A and B both have the same coefficient of friction. If a worker weighs 360 N and stands on the middle rung, determine the minimum value of the coefficient of friction so that the ladder does not slide. Neglect the weight of the ladder.
A fisherman has caught a fish on his pole, and to keep the pole steady he has to apply an upward force of F2 = 265 N at an angle of 58° with respect to the pole (see figure). The length of his pole is 3.2 m, and he is holding it a distance 0.65 m from the end, where he is applying a downward force F1. Part (a) With how much force, F1, in newtons, does he have to push straight downward on the end of his pole to keep the pole from moving? You may assume the pole is massless. Part (b) What is the mass of the fish on the end of the pole, in kilograms?
