P Determine the axial forces of the indicated members of the different truss shown and indicate whether they are in tension or compression. Determine also the number of rivets necessary to connect them in Smm gusset plate. Use 15mm diameter rivets. The allowable shearing stress is 90MPa and allowable bearing stress is 115MPa. Tabulate the final answer in the table below. Use the data according to your seat number. Seat #1 use Set A; Seat #2 use Set B; seat # 3 Set C etc... etc...
