WebMost commonly, strain is measured to determine the level of stress on the material – Experimental Stress Analysis. The absolute value and direction of the mechanical stress is determined from the measured strain and known properties of the material (modulus of elasticity and Poisson’s ratio). These calculations are based on Hooke’s Law. A common voltage for flashlight batteries is 1.5 volts (DC). A common voltage for automobile batteries is 12 volts (DC). Common voltages supplied by power companies to consumers are 110 to 120 volts (AC) and 220 to 240 volts (AC).
