A strain gauge is bended to a beam which is 12 cm long and has a cross-sectional area of 3.8 cm2. The unstrained resistance and gauge factor of the strain gauge are 220 and 2.2 respectively. On the application of load the resistance of the gauge changes by 015 2. If the modulus of elasticity for steel is 207 GN/m2, calculate: (1) The change in length of the steel beam. The amount of force applied to the beam.
