The cross-sectional area of a steel rod ...

The cross-sectional area of a steel rod of length 25 cm is 0.8 `cm^(2)`. What tension will be required to incresase the length of the rod, equal to the increase due to its rise in temeprature by `10^(@)C`?
For steel, `Y=2 times 10^(12)dyn*cm^(-2) " and " alpha=10^(-5@)C^(-1)`.

Text Solution

Verified by Experts

The correct Answer is:
`16 times 10^(7)dyn`
