Questions and Answers

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?

  • The lowest point on the object
  • The highest point on the object
  • The geometric center of the object
  • The point where the gravitational force can be concentrated (correct)

In what context do engineers mainly use the centroid?

  • To determine the balance of an object
  • To find the average position of all points in a region
  • To calculate the gravitational force acting on an object
  • To design structures and calculate moments of inertia (correct)
