A line was measured to be 2345.50 m when measured with a 30m steel tape supported throughout its length under a pull of of 8kg and at a mean temperature of 20 deg. celsius. The tape is standardized at a temperature of 35 deg. celsius under a pull of 5kg. The cross sectional area of the tape is 0.03 sq.cm, its coefficient of linear expansion is 0.0000116/deg. celsius and the modulus of elasticity is 2.0 x 10^ 6 kg/sq.cm. a) Determine the total correction due to temperature a) 0.005 m too long b) 0.408 m too short c) 0.408 m too long d) 0.005 m too short b) Determine the total correction due to pull a) 0.117 m too long b) 0.015 m too short c) 0.117 m too short d) 0.015 m too long c) Determine the correct length of the line considering the combined correction a) 2345.209 b) 2344.975 c) 2346.025 m d) 2345.791 m
