Problem 9

Given information

Given: You lean backward when carrying a heavy load in your arms.

Step-by-step explanation

Normally, when a person is standing or walking, their center of gravity (CG) is aligned with their legs. The moment a person carries a heavy load the CG of the person is unaligned from his legs (a straight line joining the CG with the legs), this way due to the heavy load an additional torque is generated that tends to move the body forward.
