Question 1

Two parallel rails are running on railway sleepers. The centre-to-centre distance between the rail is ‘b’ with the sleepers projecting by an amount ‘a’ at each end beyond the rails. When the train passes over the rails, the reaction exerted by the ground can be taken as uniformly distributed over the sleeper. The ratio b/a for the condition that the maximum bending moment is as small as possible is

Question 2

Efflorescence of bricks is due to

A cantilever beam, 3m long, carries a uniformly distributed load over the entire length. If the slope at the free end is 1 °, the deflection at the free end is

Question 4

Consider the following statements concerning engineering geology:
1) Dams on sedimentary impervious strata dipping upstream will be unsafe
2) In general, igneous rocks are hard and are suitable for construction of large hydraulic structures.
3) Construction of a major dam must be preceded by thorough geotechnical investigations.
4) Construction of dams is never indicated in any active zone of seismicity.
Which of the above statements are correct?

Question 5

Consider the following statements:
