OBJECTIFICATION OF MODULUS ELASTICITY OF FOAM

Dimensional Formula of Modulus of Elasticity and its

Modulus of Elasticity = Linear Stress × [Linear Strain]-1. Or, E = [M 1 L-1 T-2] × [M 0 L 0 T 0]-1 = [M 1 L-1 T-2] Therefore, the modulus of elasticity is dimensionally represented as [M 1 L-1 T-2]. ⇒ Check Other Dimensional Formulas: Dimensions of Newton; Dimensions of Boltzmann Constant; Dimensions of Time Period; Dimensions of Power of Lens
