Why is it necessary for the sleepers to act as an elastic structure?
A. To absorb the vibrations of moving loads
B. To make it cheap
C. It is the material’s limitation
D. To keep them intact
Explanation: Huge amount of loads and vibrations act on the rails because of the moving load. By making the sleepers elastic we ensure proper transfer and absorption of these.
The number of sleepers per rail length is called as _____
A. sleeper spacing
B. sleeper gravity
C. sleeper gradient
D. sleeper density
Explanation: The number of sleepers laid on the track per rail length is termed as sleeper density. Based on the sleeper density the spacing between sleepers is calculated. The maximum traffic on a route has an impact on its sleeper density.
