PHYS 1443 – Section 501 Lecture #1
... 1. Hang the object by one point and draw a vertical line following a plum-bob. 2. Hang the object by another point and do the same. 3. The point where the two lines meet is the CM. Since a rigid object can be considered as collection of small masses, one can see the total gravitational force exerted ...
