**Problem Statement:**A cook holds a 1.30 kg carton of milk at arm's length. What force \( F_B \) must be exerted by the biceps muscle? (Ignore the weight of the forearm.)**Diagram Explanation:**The image shows a human arm holding a carton of milk, represented at the left end. The diagram highlights two forces acting on the system:1. \( F_g \) - The gravitational force acting downward at the hand, vertically aligned with the milk carton.2. \( F_B \) - The force exerted by the biceps, shown as a diagonal arrow originating from the biceps region, angled at \( 75.0^\circ \) from the horizontal.Distances marked on the forearm:- From the point of force \( F_g \) to the elbow (point of rotation) is 25.0 cm.- From the elbow to the point of force \( F_B \) is 8.00 cm.

First, we see the diagram and understand the problem. So, For rotational equilibrium, we have to…

Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).

Question

**Problem Statement:**
A cook holds a 1.30 kg carton of milk at arm's length. What force \( F_B \) must be exerted by the biceps muscle? (Ignore the weight of the forearm.)

**Diagram Explanation:**
The image shows a human arm holding a carton of milk, represented at the left end. The diagram highlights two forces acting on the system:

1. \( F_g \) - The gravitational force acting downward at the hand, vertically aligned with the milk carton.
2. \( F_B \) - The force exerted by the biceps, shown as a diagonal arrow originating from the biceps region, angled at \( 75.0^\circ \) from the horizontal.

Distances marked on the forearm:
- From the point of force \( F_g \) to the elbow (point of rotation) is 25.0 cm.
- From the elbow to the point of force \( F_B \) is 8.00 cm.
