Explanation:
The given data :-
- Diameter of rod AB ( d₁ ) = 200 mm.
- Diameter of rod BC ( d₂ ) = 150 mm.
- The linear co-efficient of thermal expansion of copper ( ∝ ) = 1.6 × 10⁻⁶ /°C
- The young's modulus of elasticity of copper ( E ) = 120 GPa = 120 × 10³ MPa.
- Consider the required temperature increase to close the gap at C = T °C
- Consider the change in length of the rod = бL
