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.

Question

The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of the forearm about 2.15 cm beyond the joint. Assume the forearm has a mass of 2.15 kg and a length of 0.405 m.

**Diagram Explanation:**
- The diagram shows a side view of a human arm.
- The humerus is labeled as the upper arm bone connected to the shoulder.
- The elbow is the joint that connects the humerus to the forearm.
- The forearm consists of the radius and ulna, with the radius on the thumb side.
- The biceps muscle is shown connecting the humerus to the forearm, pulling upward.
- The hand is holding a square labeled "M," representing a mass.

When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass 4.95 kg so that her forearm remains motionless, what is the force \( F \) exerted by the biceps muscle?

\[ F = \underline{\hspace{2cm}} \, \text{N} \]
