Subjective Type
Explain the following : $$ (a) $$ Sleepers are used below the rails $$ (b) $$ A tall building has wide foundations.
Solution
(a) Sleepers are laid below that rails reduce pressure ( force / area) on the ground.
$$ \therefore $$ Sleepers increase the area.
(b) Foundation of buildings are kept wide so that the weight of the building may act on larger area. as a result will exert less pressure on the ground. this avoids sinking of building into the earth.
