Question

Which of the following statements is true about a body's center of gravity:

a. It is the location of the area center

b. It is the point where the potential energy of a system is minimal.

c. It is the point where the weight resulting from a system acts in such a way that it generates the moment resulting from a system.

d. It is the location where the moment resulting from a system subject to symmetrical couplings acts.

Answer 1

Answer : the following statements is true about a body's center of gravity :

(c) It is the point where the weight resulting from a system acts in such a way that it generates the moment resulting from a system.

Because, The center of gravity of a body is described as its balance point or that point about which a body would balance without a tendency to rotate. For this reason, the center of gravity is often identified as the point where all the weight of the body or object is concentrated. More accurately, it is the point where the weight of the body may be said to act.
