Answer

Young's modulus is not used to measure the strength of materials. Young's modulus measures the ability of a material to resist deformation when a stress is exerted on a material. If Young's modulus for diamond is 20 times as large as that of glass, then this shows that it is much more difficult to deform diamond than glass.

Work Step by Step

The strength of a material is the amount of stress that can be exerted on a material before it deforms to a point where it will not regain its original shape once the stress is removed. However, Young's modulus is not used to measure this property of materials. Young's modulus measures the ability of a material to resist deformation when a stress is exerted on a material. If Young's modulus for diamond is 20 times as large as that of glass, then this shows that it is much more difficult to deform diamond than glass.
