or size known as strain Upon removal of the force the material returns to its original configuration 11 Stress and Strain Stress Stress is a measure of the internal forces acting within a deformed material It is defined as the force applied per unit area Strain Strain represents the deformation of a material caused by stress It is measured as the change in length or volume relative to the original dimensions 12 Types of Elasticity Youngs Modulus This modulus relates stress to strain in tension or compression It quantifies 2 a materials stiffness and its resistance to elongation or shortening Shear Modulus This modulus describes the resistance to deformation caused by shear forces such as twisting or sliding Bulk Modulus This modulus measures the resistance to volume change under uniform pressure It is relevant for fluids and solids under hydrostatic conditions 2 Hookes Law and its Applications 21 Hookes Law This fundamental law of elasticity states that within the
