Question

A surveyor’s 30 m steel tape is correct at a temperature of 20°C. The distance between two points, as measured by this tape on a day when the temperature is 35°C, is 26 m. What is the true distance between the points?αsteel =1.2×105/C

Easy
Solution

Let temperature above the correct temperature be
 θ=3520=15C (Using the relation)
Correct length = measured length(1+αθ)
True distance between the points = 26(1+ 1.2 x10-5 X1.5)
  True distance =26.00476m
