Analysis of Forces on a Truss
A truss is a structure made of triangular units, commonly used in bridges and roofs. The forces acting on a truss are calculated from the conditions of static equilibrium; for example,
means the force exerted on the pin located at
by the strut
.

DETAILS
The equations to solve are:
(normal forces in A and E and the load)
(torque about the point A)
(vertical forces in A)
(horizontal forces in A)
(vertical forces at C)
(horizontal forces on B)
