Explain why, wooden (or concrete) sleepers are kept below the railway line.

Lakhmir Singh Physics Class 9

Answer 1

Explanation:

wide wooden sleepers are placed below the railway tracks so that the pressure exerted by the rails on the ground becomes less. therefore, increase in area decreases the pressure .

Answer 2

Dear Student,

# Wooden/concrete sleepers are kept below the railway line because -

• Railway line have to carry very high weighing trains over it.
• If rails are directly put on the ground, it will be shoved in the soil due to high thrust.
• Hence, wooden/concrete sleepers are kept below the railway line so that thrust will get distributed over large area.

Thanks dear. Hope this helps you...
