A single strain gauge having resistance of 150N is mounted on a steel cantilever beam at a distance of 0.2m from the free end. The beam dimensions are 30 cm (length) x 1.8 cm (width) x 0.28 cm (depth). An unknown force F applied at the free end produces a deflection of 11 mm at the free end. If the change in gauge resistance is found to be 0.152. Calculate the gauge factor. Take Young's modulus of steel as 200 GN/m²?. 4(a)

Part-C
A single strain gauge having resistance of 150 Q is mounted on a steel cantilever beam
at a distance of 0.2m from the free end. The beam dimensions are 30 cm (length) x 1.8
cm (width) x 0.28 cm (depth). An unknown force F applied at the free end produces a
deflection of11 mm at the free end. If the change in gauge resistance is found to be
0.15N. Calculate the gauge factor. Take Young's modulus of steel as 200 GN/m2.
