INNAT2 marksNeeds review
A metallic strain gauge of resistance
with a gauge factor of 2 is bonded to a structure made of a metal with modulus of elasticity of 200 GN/m
. The value of
is 1 kΩ when no stress is applied.
is a part of a quarter bridge with three identical fixed resistors of 1 kΩ each. The bridge is excited from a DC voltage of 4 V. The structure is subjected to a stress of 100 MN/m
. Magnitude of the output of the bridge (in mV, rounded off to two decimal places) is ____Log in to check the answer
