2. A standard steel tape of length 30 m and cross-section 15 x 1.0 mm was standardised at 25°C and at 30 kg pull. While measuring a base line at the same temperature, the pull applied was 40 kg. If the modulus of elasticity of steel tape is 2.2 x 106 kg/cm2, the correction to be applied is
Correct Answer: gradual increase of super-elevation from zero at the tangent point to the specified amount at the junction of the transition curve with main curve
6. The bearings of two traverse legs AB and BC are N52° 45' E and N34° 30' E respectively. The deflection angle is
