Show that the circumferential strain measured. by a transverse gage on a round bar is the same as the radial strain. Explain why this is consistent with our definition of Poisson's ratio equal to the ratio of perpendicular strain to parallel strain. The strain indicators read in units of microstrain (10%). If a strain gage with a resistance of 120 ohms is used and the gage factor is 2.175, what resistance change corresponds to a strain of 250μe (250 x 10-)?
