No calculator

Use a rigid weightless bar, a frictionless fixed hinge, vertical forces and a slow small turn from horizontal unless the question asks about limits of this ideal model

A horizontal bar has a fixed hinge at the left, a load in the middle and input at the right end

The input end moves up through a small turn while the hinge stays fixed
