STEEL is most elastic among the rubber, steel, glass and sponge. Steel having the most steep linear stress-strain curve among all.
A stiffer material will have a higher elastic modulus.
Young’s Modulus alt. Modulus of Elasticity – is a measure of stiffness of an elastic material.
Young’s modulus for steel- 200 GPa
Young’smodulus for glass – 50–90 GPa
Young’s modulus for rubber – 1 MPa
Young’s modulus for sponge – 2–4 GPa
A material with a higher Young’s modulus is more elastic.Lack of _______ causes diabetes?
