How do you dervive Hooke's law for the stress and strain components? This question pretains to the error in a measurement due to strain when using a long tape measure and that error is L-L0 . Where the error is introduced in inches into the measurement at a L length if the tape is pulled with P N (force) attached contains the question.

For a conductive wire with length L=1cm,w=1mm, h=1mmunder uniaxial strain, the resistance change is given as. If the uniaxial strain is e= 1 and the Poisson’s ratio is n= 0.3. What is the gauge factor?
A strain gauge is used to measure the tension force in a 2-cm diameter bar of steel with Young modulus of 2.07 x 107 N/cm2 (30 x 106 lb./in.2). The strain gauge has a nominal resistance of 160 Ω and a GF of 5. The gauge is connected to a bridge supplied with a 10 Vdc. The bridge was initially balanced. After the bar is put under tension, the bridge output voltage is 0.0008 Vdc. Draw the schematic of the bridge (setup). Calculate the force on the bar.
Semiconductor strain gauges find their primary application in the construction of transducers, such as load cells and pressure transducers.

SOLVE CAREFULLY!! Please Write Clearly and Box the final Answer
Answer must be coorect -- when using three-wire connections to a strain gage to reduce the effects of leadwire resistance changes with temperature, a phenomenon called leadwire desensitization can occur. If the magnitude of the leadwire resistance exceeds 0.1% of the nominal gage resistance, significant error can result. Assuming a 18-gauge (AWG) platinum leadwire (resistivity 10.6×10-8 S2m) and a standard 120 22 gage, how long can the (individual) leads (in inches) be before there is leadwire desensitization?
