Q3 A resistance strain gauge with a gauge factor of 2.4 is mounted on a steel beam whose Young's modulus of elasticity is 2x106 Kg/cm2. The strain gauge has an unstrained resistance of 1200 which increases to 120.10 when the beam is subjected to a stress. Calculate the stress at the point where the strain gauge is mounted.

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
