A surveyor’s 30.0-m steel tape is correct at 20.0o C. The distance between two points, as measured by this tape on a day when its temperature is 5.00o C, is 25.970 m. What is the true distance between the points?
Step 1 of 3
Solution 80P 0 We have to measure the distance between the two points at 20 C . Therefore, temperature difference T = 20 5 C = 15 C 0 6 0 The coefficient of linear expansion of steel is = 12 × 10 / C 0 The distance at 5 C is L = 25.970 m. 0 Therefore, when the temperature rises to 20 C , the change in length is L = LT L = 25.970 m × 12 × 10 6 / C × 15 C0 L = 0.0046 m 0 So, the true length at 20 C is = 25.970 m + 0.0046 m = 25.9746 m
