hey i got a question. i have a beam that is cantilevered at both ends. there is a force acting at both edges of the beam where it is joined to the support. These forces will not impose a bending moment since there is no moment arm, so what is the shear stress caused from these forces? just force/area? LMK thanks for the help!!!

You got it... P/A=shear

If the downward forces are acting right above the beam supports, then there won't be any shear stresses.

nah its just inside the supports, but the distance away would be so small that the bending moment would be negligable. also it should be noted that the supports prevent all movement including rotation. Thanks for all the responses!
