How to do force analysis for various joints/links to choose perfect motors and link materials

Hi all
I’m planning to build a robotic arm, and I’m confused about how to do force analysis for various joints/links to choose the perfect motors and link materials for my robot. Any help and suggestion will be highly appreciated.

It’s simplified in that it doesn’t include inertia and is only for a 4 axis robotic arm, but still.
