(a) Consider a strain gauge with nominal resistance of 150Ω. It is glued on the surface of a structure. The structure deforms nominally 0.001 strain level ( = Δl∕l = 0.001). Assume that the gauge factor of the strain gauge is 2.0. Determine the change in the nominal resistance of the strain gauge under this condition. The gauge factor is defined as GF=(δR/R)/ϵ (b) Design a circuit to measure the strain as proportional voltage output to a data acquisition board which has 0–5V input range. When the strain level is 0.001, the output voltage should be 5.0V.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
