Question

answer all and dont give only first

b) As an engineer in a factory, you are supposed to construct a strain guage. List ten (10) desirable factors that your selection of grid materials will be based on. c) Show that for a balanced Wheatstone bridge circuit R1 R4 R2 R3 d) Also the output voltage of an unloaded symmetrical resistance bridge is given by the equation: V AR Va =-x R Show that, V = V AL X K e) A single 100V resistance strain guage having a guage factor of 2 is mounted on a steel bar and is connected into a circuit. When the steel bar is subjected to a tensile force the output voltage of unloaded bridge is 5mV. If the recommended operating current of the guage is 15mA, determine the value of the mechanical strain.
