DEAR COLLEAGUES,
I am performing a beam stress calculation (that is used to dismount a motor wich weight is 1000 pounds).The beam is horizontally supported by 5/8" bolts in three points. I have performed calculation for the beams, i have got it the moments reaction and vertical reactions on supports.
My doubts is not in beam stress verifaction,my conceptual doubt is on Bolt stress verification, te worst case is on the cantilver part of the beam maximun span 31.5inch so the maximun moment is acting on support M=1000p*31.5inc. My question is, if the load is acting axially on the bolt but eccentric e=31.5 the stress on the bolt is always tension or the stress acting is from bending action so the S=M/W is right?
Or the bolt always is calculated as tensile stress S=Load/area?
I am attaching a ppt file to clarify my doubt
Kind regards
