Figure P-130 shows a roof truss and the detail of the riveted connection at joint B. Using allowable stresses of τ= 70 MPa and σb= 140 MPa, how many 19-mm diameter rivets are required to fasten member BC to the gusset plate? Member BE? What is the largest average tensile or compressive stress in BC and BE?
