How can you apply equilibrium to find the forces you need for design?

We’re into the realm of the ‘rigid body’.

Sometimes you can find what you need from symmetry. But for most cases you’ll need something more. You’ll need to consider the twisting effects of forces.

This video introduces these concepts, and shows you why you need them for design.
