| Multiple-Concept Example 4 reviews the concepts that are in-volved in this problem. A ruler is accurate when the temperature is 25 °C.When the temperature drops to - 14 °C, the ruler shrinks and no longermeasures distances accurately. However, the ruler can be made to readcorrectly if a force of magnitude 1.2 × 10° N is applied to each end soas to stretch it back to its original length. The ruler has a cross-sectionalarea of 1.6 X 10-$m², and it is made from a material whose coefficient oflinear expansion is 2.5 × 10-s (C°)-'. What is Young's modulus for the*20.material from which the ruler is made?

Given: The accurate temperature for rule is T1=25oC. The final temperature is T2=-14oC. The force…
