Steel expands 1 part in 100,000 for each Celsius degree increase in temperature. If the 1.5-km main span of a steel suspension bridge had no expansion joints, how much longer would it be for a temperature increase of
The linear expansion of steel for the given temperature change.
Answer to Problem 65A
The linear expansion of steel for
Explanation of Solution
Given:
Linear expansion coefficient of steel for 1 part ,
Original length ,
Formula used:
The linear expansion is given by the formula,
Calculation:
On substituting the values in the above equation,
Now,
By multiplying the length of the bridge by that ratio,
Therefore, the steel is
