Define Bulk modulus of a material.

1.	Define Bulk modulus of a material.
Answer» Bulk Modulus\tBulk modulus is the ratio of hydraulic stress to the corresponding hydraulic strain.\tDenoted by ‘B’\tB = -p/(ΔV/V)\xa0\tWhere p =hydraulic stress, ΔV/V = hydraulic strain(-) ive signs show that the increase in pressure results in decrease in volume.\tS.I. Unit :- N/m2 or Pascal(Pa)\tB(solids) > B(liquids) >B(gases)
