🌧️ What Is Stress And Strain

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). In the language of physics, two terms describe the forces on objects undergoing deformation: stress and strain. Stress is a quantity that describes the magnitude of forces that cause deformation. Stress is generally defined as force per unit area. nJ3j.
