Question

A rod is fived between two points at 20° The Coefficient of linear expansion of material of rad is 1.1 cross times 10 to the power of negative 5 end exponent divided by to the power of 0 straight C  and Young's modulus is 1 comma 2 cross times 10 to the power of 11 straight N over straight m squared . Find the stress developed in the rod if temperature of rod becomes 10°

  1. 1 comma 32 cross times 10 to the power of 7 straight N over straight m squared
  2. 1.10 cross times 10 to the power of 15 straight N over straight m squared
  3. 1.32 cross times 10 to the power of 5 straight N over straight m squared
  4. 1.10 cross times 10 to the power of 6 straight N over straight m squared

The correct answer is: 1 comma 32 cross times 10 to the power of 7 straight N over straight m squared
