First, one must draw a picture or have access to a diagram. Then, one may utilize a list of force and momentum equations. With this list, one will create five equations with five variables: Ax, Ay, Az, bc (C), and bd (D). The list of equations can be entered into a scientific calculator in the form of a matrix and the variables can be solved for. The equations will look like:
4C+2D+0+0+0=981N
-2C+4D+0+0+0=0
C-2D+Ax+0+0=0
-2D-2C+0+Ay+0=0
2C+D+0+0+Az=981N
Ax=0, Ay=589N, Az=490N bc=294N, bd=589N
