1. Five forces are applied to the solid prism shown in Figure 1.
Note that the 30 lb forces are in the plane of the prism's
surface and are not vertical. Also note that the end of the
prism is not an equilateral triangle.
a) Compute the magnitude of the couple moment of the
force couple formed by the 30 lb forces.
b) Replace all the forces with an equivalent resultant force
and couple moment acting at point A, Rand G. Give
your answers as Cartesian vectors.
