Concept explainers

Center of Gravity and Centroid

The term center of gravity indicates the position or location of a point about which the whole weight of a body or system is supposed to be concentrated, which means the whole weight of the body or system works through this point. It is closely related to mass distribution. For all positions of the body, the center of gravity would be a single point.

Question

19 - Obtain the center of gravity of the surface area of the plane plate of constant thickness in the given set (x,y).

Dimensions

where a = 12 m, b = 23 m and r = 3 m,

the center of the circle is at the point (2a, 1/2 b).

Which of the following is the correct coordinate of the center of gravity of the plate on the x-axis?

A) 19.05

B) 10.87

C) 17.14

D) 13.34

E) 19.94
