Conversion factors are 1psi = 6895Pa and 1Pa = 1.450 × 10−4psi 1atm = 1.013 × 105Pa = 14.7psi. 1 psi = 6895 Pa and 1 Pa = 1.450 × 10 −4 psi 1 atm = 1.013 × 10 5 Pa = 14.7 psi. An object or medium under stress becomes deformed. The quantity that describes this deformation is called strain.
In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing).

The relation between stress and strain is that they are directly proportional to each other up to an elastic limit. Hooke’s law explains the relationship between stress and strain. According to Hooke’s law, the strain in a solid is proportional to the applied stress and this should be within the elastic limit of that solid. Q4.
