Poisson's ratio is the relation between lateral strain and longitudinal strain. Poisson ratio is depends on the material. Its SI unit is dimensionless.
Viscosity is the ratio between shear stress and rate of shear strain. Its SI unit is N-s/m^2.
Bulk modulus is the ratio between direct stress and volumetric strain. Its SI unit is N/m^2.
Stress is the ratio between force and cross-sectional area. Its SI unit is N/m^2. Where P- force A- cross-sectional area
Young's modulus is a hooks law constant. It is the ratio of stress and strain. Its depends on the stress and strain. The mechanical property of a material to withstand…
