$$ISA$$ $$100 \times 100 \times 10\,\,mm$$ (Cross sectional area $$ = 1903\,\,m{m^2})$$ serves as tensile member. This angle is welded to a gusset plate along $$A$$ and $$B$$ appropriately as shown. Assuming the yield strength of the steel to be $$260$$ $$N/m{m^2}$$ the tensile strength of the member can be taken to be approximately

Two steel plates each of width $$150$$ $$mm$$ and thickness $$10$$ $$mm$$ are connected with three $$20$$ $$mm$$ diameter rivets is placed in zig-zag pattern. The pitch of the rivet is $$75$$ $$mm$$ and gauge is $$60$$ $$mm.$$ If the allowable tensile stress is $$150$$ $$MPa,$$ the maximum tensile force that the joint can withstand is
