A person weighs 169 lb. Each crutch makes an angle of θ = 18.0° with the vertical. Half of the person's weight is supported by the crutches, the other half by the vertical forces exerted by the ground on his feet. Assuming he is at rest and the force exerted by the ground on the crutches acts along the crutches, determine each of the following. A person is shown supporting their weight on a pair of crutches, one under each arm, such that their bottom ends are farther apart than their top ends. Each crutch forms an angle θ with the vertical. (a) the smallest possible coefficient of friction between crutches and ground (b) the magnitude of the compression force supported by each crutch lb

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.
