Deformation of beams: how would beam bolted together would behave vs beam stacked on each other. I could not figure the equation out instantaneously but he asked to find the answer the same day and e-mail him. I did found the answer and e-mail the manager..
It is related to shear stress in beams. when you develop equations for Shear stress in a beam, we use this analogy to account for the presence of longitudinal shear stress in the beam. You can solve it through equations but I think they are looking for if you can explain the difference in behaviour Less
The question is more focused on parallel and series beam question.
For the parallel beam ( for your case 2 beams stacked on top of each other) the total deflection will be same.
And for the beams in series ( bolted beams together in your case) the total deflection will the summation of individual deflection of the beams Less
look up standard beam deflection formula and solve it
