1.	A steel rod of length 6 m and diameter 20 mm is fixed between two rigid support. Determine the stress in the rod, when the temperature increases by 80 ∘C and the ends yield of 1 mm is allowed.Take Young's modulus, Y=2×106 N/cm2 and thermal coefficient of linear expansion, α=12×10−6/ ∘C.
Answer» A steel rod of length $6 m$ and diameter $20 mm$ is fixed between two rigid support. Determine the stress in the rod, when the temperature increases by $80^{\circ} C$ and the ends yield of $1 mm$ is allowed. Take Young's modulus, $Y = 2 \times 10^{6} {N/cm}^{2}$ and thermal coefficient of linear expansion, $α = 12 \times 10^{- 6} /^{\circ} C$ .
