In one to three sentences each describe and what is the difference between them: Stiffness, Toughness, Strength, Young’s Modulus, and Modulus of resilience.

Solution

Stiffness is the tendency of a material to resist small deformation when the material is stressed. Toughness is the ability of a material to absorb energy when impact load is applied. i.e. toughness describes how much energy is to be used before a material breaks. Strength is measure of extent of material\'s elastic range or elastic and plastic ranges together. i.e. the strength of a material is the ability to withstand applied load without failure or plastic deformation. The Young\'s modulus or modulus of elasticity is a number that measures an object or substance\'s resistance to being deformed elastically. i.e. it is a measure of stiffness of an elastic material.The modulus of resilience is the maximum energy a material absorbed per unit volume without creating a permanent distortion.

So, the stiffness of a material depends on the modulus of elasticity (Young\'s modulus). It describes the relationship between stress and strain. Unlike strength, stiffness is unchangeable for a given material, where the strength can be changed, either by heat treatment or cold work. again tougness is related with impact load. An modulus of resilience is a measure of energy per volume..
