Please, I need the answers to the parts d) e) f) Thank you,

The figure shows a roof truss and the detail of the connection at joint B. Members BC and BE are angle sections with the thickness shown in the figure. The working stresses are 70MPa for shear in the rivets and 140MPa for bearing stress due to the rivets. How many 22mm diameter rivets are required to fasten the following members to the gusset plate: (a) BC; and (b) BE? 000 4 m B с 96 kN D 6 m E 200 KN 4 m F G 4 m 96 kN H to- PBC - -14-mm-thick gusset plate -13-mm-thick angle 6-mm-thick angle PBE
