A double riveted lap joint is made between 15mm thick plates. The rivet diameter and pitch are 25 mm and 75 mm, respectively. If the ultimate stresses are 400 MPa in tension, 320 MPa in shear and 640 MPa in crushing, find the minimum force per pitch which will rupture the joint. If the above joint is subjected to a load such that the factor of safety is 4, find out the actual stresses developed in the plates and rivets.

Question
A double riveted lap joint is made between 15mm thick plates. The rivet diameter
and pitch are 25 mm and 75 mm, respectively. If the ultimate stresses are 400 MPa
in tension, 320 MPa in shear and 640 MPa in crushing, find the minimum force per
pitch which will rupture the joint.
If the above joint is subjected to a load such that the factor of safety is 4, find out
the actual stresses developed in the plates and rivets.
