2-Triangular hook plate laser cut from 1020 HR steel plate shown in the picture is 10 mm thick and has a base length of 70 mm. Weld is made with E 6012 electrode, all around. If perpendicular to base plate load F fluctuates cyclically from +18 kN (tension) to -18 kN (compression) each cycle, and a design safety factor of 2.5 is desired under DE theory conditions and ASME elliptic failure criteria. a- What fillet weld size would you recommend if all fillet welds are to be the same size? Infinite life is desired. (20) b- If we make same functionality with the design in screw connection as in next figure what would be the minimum sized metric screw size using Goodman criteria? Screw plate base thickness is 10 mm. Assume C=0.4. (15) 70.00 15.00 40.00 15.00 40.00 50.00 18 R10.00 F= 18 kN cyclic diftorten presenty 70 mm
