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.

Textbook Question

Chapter 11, Problem 30PCE

A uniform metal rod, with a mass of 2.0 kg and a length of 1.5 m, is attached to a wall by a hinge at its base. A horizontal wire bolted to the wall 0.70 m above the base of the rod holds the rod at an angle of 28° above the horizontal. The wire is attached to the top of the rod. (a) Find the tension in the wire. Find (b) the horizontal and (c) the vertical components of the force exerted on the rod by the hinge.

A beam with a length of 2 m and a mass of 10 kg supports a 50 kg box. The beam is connected to a wall by a hinge at its base and a horizontal wire. The wire is connected to the beam 1.5 m from the hinge and makes an angle θ of 35o to the beam. The goal is to find the tension in the wire and the horizontal and vertical components of the force exerted by the hinge on the board

A 1.323-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1.575-N crate hangs from the far end of the beam. Find the magnitude of the tension in the wire. The angle theta () is 25 degrees and the angle phi () is 59 degrees. The length of the beam is L.

A uniform metal bar that has mass 4.00 kg and length 2.00 m is attached to a wall at one end by a frictionless hinge. The bar is held at an angle of 36.9 ° above the horizontal by a light horizontal rope that has one end attached to the upper end of the bar and the other end attached to a vertical wall. What is the tension in the rope?
