A horizontal beam is supported by an inclined strut and carries a load of 15 kN at joint AD CB D in the figure. The strut, which consists of two bars each of thickness 40 mm, is connected to the beam by a rivet passing through the three bars meeting at joint. The allowable shear C stress and bearing stress are all, z =60 MPa and =120 MPa, respectively. a) Determine the required diameter of the rivet at the hinge that carries safely by the given C system. b) If the diameter rivet used on the support is 20 mm check whether this rivet diameter is A sufficient for the given system.

Question
A horizontal beam is supported by an inclined strut and carries a load of 15 kN at joint AD CB
D in the figure. The strut, which consists of two bars each of thickness 40 mm, is connected to
the beam by a rivet passing through the three bars meeting at joint. The allowable shear C
stress and bearing stress are all, z =60 MPa and =120 MPa, respectively.
a) Determine the required diameter of the rivet at the hinge that carries safely by the given C
system.
b) If the diameter rivet used on the support is 20 mm check whether this rivet diameter is A
sufficient for the given system.
