Two strips of metal are riveted together at their ends by four rivets, each of diameter 6.0 mm. What is the maximum tension that can be exerted by the riveted strip if the shearing stress on the rivet is not to exceed 6.9 × 107 Pa? Assume that each rivet is to carry one-quarter of the load.

Now here the metal strips are riveted together so the stress in the rivet would be shearing stress since force would be perpendicular to surface area of rivet and stress is the restoring force per unit area, restoring force is same as applied force in equilibrium condition, the rivet joints and force on them are as shown in the figure



Now we know shearing stress is given as
