This simple truss structure consists of a set of trusses, all connected to each other joints, that is supported by a pinned connection at point A and a roller connection at point E.

This simple truss structure consists of a set of trusses, all connected to each other
by pin joints, that is supported by a pinned connection at point A and a roller connection at point
E. The four triangles that make up the overall truss are similar isosceles triangles (angles BAF,
AFB are 45 degrees and angle ABF is 90 degrees) and the structure is symmetrical about
vertical truss CF. An external downward force of 40 kips is applied at point C as shown.
Assuming this truss structure is in a state of static equilibrium, use the method of joints to
determine the magnitude of the forces in members CB and CF and indicate if these are tensile
or compressive.

The truss structure is now loaded by additional external downward forces at B and
D as shown; all else is unchanged. Use the method of sections to find the magnitude of the
force in member AB.
