In mountainous regions, railway curves are designed to ensure the safety and comfort of passengers. The maximum degree of curvature refers to the sharpest curve that can be used safely in such regions.
According to standard engineering practices for railways, the maximum allowable curve degree in mountainous regions is typically 40°.
Thus, the correct answer is option (D).
After applying the correction for elevation and temperature, the runway length is 700 m.
The corrected runway length (in m) for an effective gradient of 1% is __________ (round off to the nearest integer).
For the beam and loading shown in the figure, the second derivative of the deflection curve of the beam at the mid-point of AC is given by \( \frac{\alpha M_0}{8EI} \). The value of \( \alpha \) is ........ (rounded off to the nearest integer).
In levelling between two points A and B on the opposite banks of a river, the readings are taken by setting the instrument both at A and B, as shown in the table. If the RL of A is 150.000 m, the RL of B (in m) is ....... (rounded off to 3 decimal places).
