A simple electrical strain gauge of resistance 120Ω and having a gauge factor 2 is bond to steel having an elastic limit stress of 400MN/m 2 and modulus of elasticity is 200G N/m. Calculate the change in resistance. (a) Due to a change in stress equal to 1/10 of the elastic range; (b) Due to change of the temperature of 20 0 C if the material is advance alloy. The resistance temperature coefficient of advance alloy is 20X 10 -6 / 0 C.

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.

A single strain gauge having resistance of 130 Ω is mounted on a steel cantilever beam at a distance of 0.12m from the free end. The beam dimensions are 25 cm (length) x 2.0 cm (width) x 0.3 cm (depth). An unknown force F applied at the free end produces a deflection of 11.8 mm at the free end. If the change in gauge resistance is found to be 0.145 Ω. Calculate the gauge factor. Take Young's modulus of steel as 200 GN/m².

In the measurement of surface roughness, height of 16 successive peaks and troughs were measured from a datum and were: 25, 43, 23, 33, 19, 40, 37, 26, 35, 22, 38, 27, 36, 25, 41 and 21 µm. If these measurements were obtained over a length of 16 mm, determine: a)The C.L.A. (i.c. Ra), R.M.S and Rz values of the rough surface. b)Determine the grade of roughness in case of Ra value.
