A plastic ball is inflated enough to produce tangential stresses.

    A plastic ball is inflated enough to produce tangential stresses. Stress X = Stress Y = 2000Kpa
    The radial thickness of the material is 1.2mm brfore inflation. Find the thickness after inflation if the tensile modulus of elasticity is 3.4Gpa and the shear modulus is 1.4Gpa.

    this looks very much like a homework problem, so chance are you won't be getting the answer- "teach a man to fish"

    list your knowns and unknowns
    what equations are relevant?
    can you set up a system of as many equations as there are unknowns?

    Thanks Jehan, I have moved my post to the homework section.
