The blank term for the point where the load weight is concentrated and acts as the balancing point is:

• A. center of gravity
• B. pivot point
• C. fulcrum
• D. weight center

Answer: (A)

The main idea is that weight can be treated as acting at a single point, and balance is achieved when the moments about that point balance out. The term that describes the point where the entire weight is effectively concentrated and about which the body balances is center of gravity. In a gravitational field, the center of gravity is the point where the weight of the object can be considered to act as a single force; it determines stability and tipping: if it sits over the support base, the object is balanced, and if it moves outside the base, tipping occurs.

Pivot point and fulcrum refer to the point about which rotation occurs in a lever system, not specifically to where the weight concentrates. Weight center is not the standard term.
