Chapter 9: Q9-9Q (page 230)

Why do you tend to lean backward when carrying a heavy load in your arms?

Short Answer

Expert verified

You lean backward to keep the center of mass over your feet.

Step by step solution

Understanding center of mass

In this problem, the concept of center of mass will be used. The center of mass is the point on a component at which the total mass is concentrated.

Explanation for the backward movement of a body due to heavy load

When a particular person is carrying a heavy load, his/her body tends to move backward in order to maintain the center of mass of the body over the feet. If the center of mass of the body is in front of the feet, the person will fall forward.
