Question 1278

▼

How does the method in Fig. 6.25 work for any shaped body?

It only works for symmetric bodies
It depends on material
Because gravity aligns the CG below the suspension point regardless of shape
It requires electrical power

All forces are zero
Forces are parallel
Net moment of all forces about that point is zero
The point is at the edge

Question 1280
