## Homework Statement

For (fi)= (b/6) x*y3 +C*xy show that simply supported beam of 2L loaded concentrated load at mid span.,the stress function satisfy loading condition is (fi) .treat concentrated load as shear stress suitably distributed to shoot this function. so that intergtal of limit (h to -h) for stress stress (tou)xy= (-W/2) ..

## Homework Equations

## The Attempt at a Solution

boundary conditions 1. (sigma)yy=0 for y =h to -h

to remove constants in stress function i need one more boundary condition .. ?? any help ll be apreciated . thanks
