1.45 The figure shows a roof truss and the detail of the connection at joint B. Members BC and BE are angle sections with the thicknesses shown in the figure. The working stresses are 70 MPa for shear in the rivets and 140 MPa for bearing stress due to the rivets. How many 19-mm-diameter rivets are required to fasten the fol- lowing members to the gusset plate: (a) BC; and (b) BE?
