Centre of gravity
What is Centre of Gravity?
It is the imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. The concept is sometimes useful in designing static structures (e.g., buildings and bridges) or in predicting the behaviour of a moving body when it is acted on by gravity.
Examples of CG:
Where is the CG?
Assuming that when the plasticine blobs were placed on the pendulum, the pendulum still remains symmetrical. So, the CG is at the dotted lines where the pendulum is. At least, that's where I think the CG is...
As for a donut...
I think that the CG will be in the middle, assuming that the donut is symmetrical.
P.S If anyone knows that I am wrong or thinks I am wrong, please comment and tell me my mistake. Thank you
