TRANSCRIPT
Elasticity
• 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
