30 Different Types of Roof Trusses (Illustrated Configurations)

One end of a timber roof truss is supported on a brick wall but not securely fastened. The reaction force (R) of the brick wall on the truss can therefore only be vertical, i.e. a normal force. If the magnitude of F is 6 kN, determine the magnitude of Fz so that the resultant of F Fz is vertically down onto the wall and can be balanced by the normal force.
