Find the reactions of a rigid body (a triangular plate) at a pin and roller. The load is at an angle.
-
Find the reactions of a rigid body (a truss) at a pin and roller. All loads are either horizontal or vertical.
-
Two forces act on a bell crank. This problem has two unknown magnitudes and an unknown direction which makes it tricky to solve by the equilibrium equation method.
The solution is much simpler if three force body principle is used.

Determine the forces in the pistons of a hydraulicly operated excavator.
-
An A-frame structure supporting a force and a moment. The feet are at the different vertical positions so the solution will require simultaneous equations, unless you rotate the coordinate system.
-
An A-frame structure supporting a force and a moment. The feet are at the same vertical position, so taking moments at one foot yields the y component of the reaction at the other.
-
An A-frame structure supporting a force or a moment. One leg is a two force body.
