Calculate the shear stress of the rivet when the steel bars are subject to an axial pull of 6kN. Diagrams Note that the rivets do, in fact, strengthen the connection by pressing the two steel bars together, but this strength, due to friction, cannot be calculated easily and is therefore neglected, i.e., the rivet is assumed to give all strength to the connection.
A further increase in stress from b results in the mild steel reaching its upper yield point at c, followed by a rapid fall in stress to its lower yield point at d. The existence of a lower yield point for mild steel is a peculiarity of the tensile test, wherein the movement of the ends of the test piece produced by the testing machine does not
