A strain gauge is bounded to a beam 0.1 m long and has cross- sectional area of 4 cm?. Young’s modulus for steel is 2.7GN/m?. The strain gauge has an unstrained resistance of 240Q and gauge factor of 2. When a load is applied the resistance of gauge changed by 0.017. Calculate the change in length of the steel beam and the length of the+ . Steel beam and the amount of force applied to the beam. DA ® .
