)continuing on problem 1, assume a strain gage was bonded to the cylinder wall surface in the direction of the axial strain. the strain gage has nominal resistance r0 and a gage factor gf. it is connected in a wheatstone bridge configuration where all resistors have the same nominal resistance; the bridge has an input voltage vin. (the strain gage is bonded and the wheatstone bridge balanced before the vessel is pressurized.) develop an expression for the voltage change ∆v across the bridge when cylinder is pressurized to ∆p
