Answer:
It's to balance the forces
Explanation:
The force and mass of gravitation is balanced so the centre of mass is also balanced so the double decker bus and the crane doesn't topple off.

Explanation:
This ensures that the centre of gravity of the system may not rise up and the bus may not be toppled due to unstable equilibrium
When the passengers stand, the center of gravity rises. If it rises much it becomes unstable and may topple down.
