Pre-analysis and start-up
Analytical Approach:
Assuming plane stresses:
The two dimensional equilibrium equations are:
Unknown macro: {latex}
\begin
Unknown macro: {eqnarray}
Unknown macro: {partial sigma_x over partial x}
+ {\partial \tau_
Unknown macro: {yx}
\over \partial y} + F_x = 0
{\partial \tau_
Unknown macro: {xy}
\over \partial x} +
Unknown macro: {partial sigma_y over partial y}
+ F_y = 0
\end
Since we are ignoring the effects of gravity; there are no body forces per unit volume.
Unknown macro: {latex}
\begin
Unknown macro: {eqnarray}
F_x = F_y =0
\end
Assuming no normal stress in the y direction:
The equilibrium equation in the y direction becomes: 
τ_yx must also be a constant, therefore the equilibrium equation in the x-direction becomes:
Therefore;
Apply Boundary Conditions:
If we make a cut at "A", as indicated in the problem specification, then the stress in A must be P/A.
Therefore,
