A strain gauge is bonded to a beam 0.1 m long and has a cross-sectional area 3 m. Young's modulus for steel is 207GN/m. The strain gauge has an unstrained resistance of 240 1 and a gauge factor 2.2. When a load is applied, the resistance of gauge changes by 0.013 2. Calculate the change in length of the steel beam and the amount of force applied to the beam
