A square bar used as a mechanical link in an automated packaging machine is subjected to a tensile force F. Determine the beam stress when it is loaded in tension with force F. Determine the Factor of Safety (FOS) of the determined stress compared to yield strength. The force, dimensions and material are listed below. All answers are in SAE units. Force (F) = 8,800 lbf Length (L) = 7.50 ft Side (b) = 0.40 inch Material = Yellow Brass Cold-rolled
