What does the centroid represent in engineering mechanics?

38. What does the centroid represent in engineering mechanics?

1. The point where the sum of moments about any axis is minimum
2. The point of intersection of all internal forces in a body
3. The point of equilibrium of a non-uniformly distributed load
4. The point at which the weight of a body is expected to act

Answer

The correct answer is: D) The point at which the weight of a body is expected to act

Explanation

The centroid is the geometric center of a body or shape on whose all of the body's weight is expected to act. It is an important topic for studying structural equilibrium and stability.
