WebbThe equation for change in length is traditionally rearranged and written in the following form: F A = Y Δ L L 0. 5.34. The ratio of force to area, F A, is defined as stress (measured in N/m 2 ), and the ratio of the change in length to length, Δ L L 0, is defined as strain (a unitless quantity). Webb1 apr. 2024 · The stress is the quotient of the tensile force divided by the cross-sectional area, or F / A. The strain or relative deformation is the change in length, Ln − L0, divided by the original length, or ( Ln − L0 )/ L0. (Strain is dimensionless.) Thus Young’s modulus may be expressed mathematically as WebbThe modulus of rigidity if the top of the cube is displaced by 0.05cm with respect to its bottom is. Solve Study Textbooks Guides.
