Which mechanical property determines the stiffness of a material?

Answer: Modulus of elasticity. Stiffness: Stiffness is a structural property of a material which offers resistance to deformation when an external load is applied. The unit of stiffness is N/m (Newron/meter). But Young’s modulus or modulus of elasticity determines the stiffness of a material. To understand stiffness in a simple way, For example, consider, two…
