R2 + V. 2. Given: A Wheatstone bridge circuit is constructed to measure strain in a component of a truss beam on a bridge. R • All resistors and strain gages are nominally 120 ohms. • The strain gage factor is 2.05. V, • The supply voltage to the bridge is 6.00 V. • With no load, the bridge is balanced (V. = 0). R4 • An axial strain of 350 ustrain is applied such that the strain gage is in tension. (a) To do: Calculate the output voltage in mV when resistor 2 is the strain gage. (b)To do: Calculate the output voltage in mV when resistors 1 and 2 are the strain gages, and both strain gages are in tension with &a = 350 ustrain. (c) To do: Calculate the output voltage in mV when resistors 1 and 3 are the strain gages, and both strain gages are in tension with &u = 350 ustrain..
