What is the main difference between center of gravity (CG) and centroid?
What is the main difference between center of gravity (CG) and centroid?
- Center of gravity focuses on equilibrium and stability, while centroid is about finding the center of mass or area of a shape. (correct)
- Center of gravity is used in structural analysis, while centroid is crucial in designing structures to prevent tipping.
- Center of gravity represents the 'center' of a shape, while centroid is the point where an object would balance if suspended.
- Center of gravity is the average position of all points in a shape, while centroid is the point at which the gravitational force can be concentrated.
Which point is considered the center of gravity for an object?
