- The Beam Shown Is A Stepped Flat Bar Having A Constant Thickness Of 1 20 In It Is Subjected To A Repeated Tensile Forc 1 (41.61 KiB) Viewed 41 times
The beam shown is a stepped, flat bar having a constant thickness of 1.20 in. It is subjected to a repeated tensile force in the range from 7200 lb to 14400 lb. Use Goodman criterion to compute the resulting design factor for the right big hole D (2.50-in diameter) and fillet at point E. The beam is made from SAE 1040 Wrought steel (surface condition: polished). Take reliability as 90%. Stress concentration needs to be considered.
