The eccentric riveted joint in the figure is loaded with a load of 100kN, applied at a distance of 250mm in relation to the geometric center of the riveted joint. It is known that the riveted sheets are 8 mm thick and that the allowable shear stress is 105 MPa, and the allowable crushing stress is 225 MPa. Determine the diameter of the rivets needed to secure the riveted connection.
