Since we are ignoring the effects of gravity; there are no body forces per unit volume.
Assuming plane stresses:
The two dimensional equilibrium equations are:
Since we are ignoring the effects of gravity; there are no body forces per unit volume.
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,
