## Homework Statement

My prof gave us this take home quiz to complete to prepare for our actual quiz. We are studying Shear force due to bending of beams (2nd year mech eng). In this question he told us that the shear force (V) can be applied at any of the points and that we would need to find the shear force due to bending (Tau). I am having the hardest time just even starting out, I need some direction on how the problem would change depending on which force point is chosen. Note: only one force will be present, either at A,B,C,D,or E.

this is the cross section given:

## Homework Equations

Tau= VQ / Ib

V = max shear force (which u find from the Shear force diagram)

Q = first moment of area

I = second moment of area

b= thickness of cross section
