Concept explainers

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.

(c) The athlete asks if it would be safe for them to do a squat. The doctor reiterates that they cannot put more than 240 N of
force through the tendon. If the athlete weighs 70 kg and we assume all the force is transmitted straight through both of their
Achilles tendons, is it safe for them to do a squat? Hint: Each Achilles tendon will bear half of the athlete's weight.
Yes
No
