What force is needed to shear a mild steel plate of thickness 0.7 mm and width 1.0 m if the shear strength of the steel is 200 MPa?

Calculate the forces required to shear the rivets in (a) a lap joint and (b) a double cover butt joint if the rivets have a diameter of 25 mm. The shear strength of the rivet material is 330 MPa.
