B.) A line MQ was measured to be (2582.45 m) using a (30-m) steel tape supported throughout its length under a pull of (5.5 kg). The mean temperature during the measurement is (33° C). The tape used has a cross-sectional area (0.03 cm) and has a standard length at (20 C) under a pull of (9 kg). The modulus of elasticity of the tape is (2x10 kglem?) and the coefficient of thermal expansion is (0.0000116 C). Find the total correction and the corrected length of the line? (25Marks)

B.) A line MQ was measured to be (2582.45 m) using a (30-m) steel tape supported throughout its
length under a pull of (5.5 kg). The mean temperature during the measurement is (33° C). The tape used
has a cross-sectional area (0.03 cm) and has a standard length at (20°C) under a pull of (9 kg). The
modulus of elasticity of the tape is (2x10 kg/em) and the coefficient of thermal expansion is
(0.0000116"C). Find the total correction and the corrected length of the line?
