A strain gauge is used to measure the shear strain on a shaft during torsional loading. The strain gauge is mounted such that it measures strain at an angle of 45° to the longitudinal axis of the shaft. The shear strain in the shaft is determined: a. as the strain measured by the strain gauge O b. by dividing the strain measured by the strain gauge by the shear modulus O c. None of these options O d. as twice the normal strain determined by the strain gauge.
