NORMAL TENSION. A steel tape having a cross-sectional area of 0.06 cm2 and a modulus of elasticity of 2.0x106 kg/cm2, weighs 0.03 kg/m. Its length is 30.00 m when standardized at a pull of 5 kg and supported throughout its length. Determine the tension at which the effect of sag will be eliminated by the elongation of the tape due to increased tension.
