• A solid may change its dimensions by three ways:

• I Tensile Stress (Stretching)

• II Shearing Stress

• III Hydrostatic Stress

• Stress (or deforming force)/unit area produces a

Strain(or unit deformation) Stresses and Strains

Stress is proportional to Strain ( Hooke’s Law)

Stress=Modulus x Strain
