Q) A steel bar of 5 mm is heated from 25°C to 45°C and it is free to expand. The bar will induce
Solution:
Stress is nothing but the resisting force since due to temperature rise body will expand and if this expansion due to temperature change is restricted then only resisting stress (thermal stress) will come into play since expansion is not restricted that's why no stress is occurring.
