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.

In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder as in the figure below. His 1.60-kg forearm remains in a horizontal position and the strap makes an angle of ? = 47.0° with the horizontal. Assume the forearm is uniform, has a length of ℓ = 0.332 m, assume the biceps muscle is relaxed, and ignore the mass and length of the hand. A person with a broken left forearm faces out of the page. His left forearm is approximately horizontal, and a strap extends from a clip on his right shoulder to a position on his left arm that is a distance ℓ from the elbow. The strap is at an angle ? above the forearm. A force vector R acts up and to the right on the left forearm at a location just left of the elbow. (a) Find the tension in the strap. N(b) Find the components of the reaction force exerted by the humerus on the forearm. (Assume the positive x-direction is to the right and the positive y-direction is upward.) Rx = N Ry= N
