Axial deflection (∆) of a tapered bar
For Circular bar
Where P = External load applied to the bar
L = length of the bar
E = Modulus of elasticity
Young’s modulus or modulus of elasticity(E)
Young’s modulus or modulus of elasticity(E) is defined as the ratio of longitudinal stress and longitudinal strain
Young’s modulus=(longitudinal stress)/(longitudinal strain)
Modulus of rigidity(G)
Modulus of rigidity(G) is defined as the ratio of shear stress and shear strain
Modulus of rigidity=(shear stress)/(shear strain)
Bulk modulus (K)
Bulk modulus (K) is defined as the ratio of direct stress and volumetric strain.
