Cantilever Beam subjected to shear stress

AI Thread Summary
The discussion focuses on determining the stress function psi for a cantilever beam subjected to shear stress. The user seeks assistance with boundary conditions necessary for solving the problem, specifically at the free end of the beam. They have identified the relevant equations but struggle with the boundary conditions. The equations derived include relationships involving constants A, B, C, D, and E, which are critical for the solution. The conversation highlights the importance of correctly establishing boundary conditions to proceed with solving the stress function.

Homework Statement


A cantilever beam (length, L, height, 2h, thickness 1). The top surface is subjected to shear stress tsubxy = s. Determine the stress function psi. The boundary conditions at the end of the free end (x=L) can be satisfied by integration (e.g., traction free can be expressed by integral from -h to h of sigma x dy = 0).


Homework Equations



Y runs vertical along the wall. X entends to the right. The shear stress runs along the +x direction.

The Attempt at a Solution



The only thing I need are the boundary conditions. I can solve for psi and the constants as long as I have the starting equations found from the boundary conditions. I am terrible at boundary conditions!

Got the boundary conditions! And now I'm working on solving the constants from these equations:

-B - 2Dx + 2Eh = 0
2A + 6Cx - 2Dh = 0
-B - 2Dx - 2Eh = -sx/I
2A + 6Cx + 2Dh = 0

Odd system of equations.
