Question
The figure shows a roof truss and the detail of connection at joint I. The allowable stresses are 70 MPa for shear and 120 MPa for bearing. How many 20-mm diameter rivets are required to fasten member IG to the gusset plate? What is the required area for member AI if the allowable axial stress is 180 MPa.
