Question
Give scientific reason for the following:
In a doubled decker bus passengers are not allowed to stand in the upper deck.
Solution
Passengers are usually advised not to stand in the upper deck of the double deck bus. When the passengers are standing, the C.G. rises. This decreases the stability of the bus. When the passengers are sitting, the C.G. gets lowered and stability of the bus increases.
