Q#3: A steel Tape was exactly 30m long at 22°C when supported throughout its length under a pull of 10kg. A line was measured with this tape under a pull of 16kg and a mean temperature of 33°C and found to be 980m long. The cross sectional area of the tape was 0.035cm² and its total weight was 0.695kg. Coefficient of thermal expansion (a ) is 1lx10^-6/°C and modulus of elasticity is 2.1x10^6kg/cm² . Compute the length if the tape was supported during measurement. (i) At every 30m (ii) At every 15m

Q#3: A steel Tape was exactly 30m long at 22°C when supported throughout its length under a
pull of 10kg. A line was measured with this tape under a pull of 16kg and a mean temperature of
33°C and found to be 980m long. The cross sectional area of the tape was 0.035cm2 and its total
weight was 0.695kg. Coefficient of thermal expansion (a ) is 11x10^-6/°C and modulus of
elasticity is 2.1x10^6kg/cm2 . Compute the length if the tape was supported during measurement.
(i) At every 30m
(ii) At every 15m
