Question 2(a): A steel surveyor's tape is to be used to measure the length of a line. The tape has a rectangular section of 2 cm by 0.5 cm and a length of 100 cm when I, and the tension or pull on the tape is AA N. Determine the true length of the line if the tape shows the reading to be BB cm when used with a pull of CC Nat Iz. The ground on which it is placed is fiat. °C P P Take: T1 = 55 T2 = 85 °C AA= 20 N BB = 463.2 CC= 35 N 2. = 12/10-6)/°C E = 200 GPa 2 cm = cm 0.5 cm = = st
