Calculate the plane stresses involved where two pieces of steel are welded together. Our sign convention defines forces causing the object to be in tension positive and forces causing the object to be in compression negative. As we can see from the picture our

σx = −4.5MPa and σy = 10MPa. Steel has an average Young’s modulus of elasticity of E = 200 GPa and an average Poisson’s ratio of ν = .285 Because it is not defined we will assume that initially there is no shear stress, τxy = 0.

Solve only for: Compression in the x-direction(deformation along the weld)=(-Blank 4)? x 10^-5
