Elasticity: Young’s modulus & Hooke’s Law
Stress: force exerted per unit area of surface on an extended object. STRESS LEAD TO STRAIN Three types of deformation due to strain: Stretching (change in length) Twisting (change in angle) Compression or Expansion (change in volume) ***Each of these strains is caused by a different form of stress Tensile stress= Stretching Shearing stress= Twisting…
