A single strain gauge is bonded to a beam 0.1 m long and has a cross section area 4 cm². Young modulus for steel is 207 GN/m². The strain gauge unstrained resistance of 250 2 and a gauge factor of 2 when a load is applied the resistance of gauge change by 0.013 2. Calculate the change in length of the steel beam and the amount of force applied to the beam.
