Firstly I want you to solve problem 8.18,but it need the problem 8.17;please help me.I have found the answer to the required question 8.17, which is:Longitudinal strain=0.0005Transverse strain =0.00125Iam not sure about that. I will attach a picture to Question 8.17 and 8.18 for you to check the numbers yourself.This question from measurements instrumentation course. A steel bar has a cross-sectional area of 103 m², Young's modulus of 2 × 10" Pa andPoisson's ratio of 0.4. If the bar is subject to a compressive force of 10° N, find the correspondinglongitudinal and transverse strains.8.17 8.18Two strain gauges, each with an unstrained resistance of 120 Q and a gauge factor of 2.0, arebonded onto the steel bar of Problem 8.17 so that one measures the longitudinal strain andone the transverse strain. Find the corresponding gauge resistances for the longitudinal andtransverse strains.

A steel bar has a cross-sectional area of 103 m², Young's modulus of 2 × 10" Pa and
Poisson's ratio of 0.4. If the bar is subject to a compressive force of 10° N, find the corresponding
longitudinal and transverse strains.

Two strain gauges, each with an unstrained resistance of 120 Q and a gauge factor of 2.0, are
bonded onto the steel bar of Problem 8.17 so that one measures the longitudinal strain and
one the transverse strain. Find the corresponding gauge resistances for the longitudinal and
transverse strains.
