strain gauge is applied to a hook from which a load is suspended. The hook is circular in cross section and is subjected to a $120$MPa longitudinal stress.The gauge is installed in a $$ bridge configuration, has resistance of $3500$ and the bridge is driven by a $24$V supply.$($a$)$ Find the bridge output assuming that R$3=$ R$2$ and R$4=$ Ro$,$ and verify thatthe gauge current will be less than $50$mA $($its maximum rated value$)($b$)$ If the gauge were at right angles to the applied stress, what output would the bridge give?Additional Information:Young's Modulus: $205$GPaPoisson's Ratio: $0\mathrm{.}3$Gauge Factor: $2$
