A ruler is accurate when the temperature is 23.1 °C. When the temperature drops to -12.6 °C, the ruler shrinks and no longer measures distances accurately. However, the ruler can be made to read correctly if a force of magnitude 1.91 x 109 N is applied to each end so as to stretch it back to its original length. The ruler has a cross-sectional area of 1.97 x 10-5 m?, and it is made from a material whose coefficient of linear expansion is 2.5 × 10-5 (C°-1. What is Young's modulus for the material from which the ruler is made?
