Answer 1

Refer to the attached image.

Answer 2

Answer:

Thermal expansion or extension or strain due to the increase in temperature

= Delta L = L × a × (100° - 0°) = strain

= 100 a L

Thus strain and the stress produced in the material due to its ends being tightly held are related by Young's modulus Y.

Stress = Y × strain = 100 a L Y
