Why luggage on roof of bus is tied with rope?

While the bus is moving, luggage tends to remain in inertia of motion state. When the bus stops, the luggage tends to resist the change and due to inertia of motion it moves forward and may fall off. That’s why it is advised to tie any luggage kept on the roof of a bus with a rope.

On what factors does the position of centre of gravity depends?

The position of the centre of gravity of a body of given mass depends on its shape i.e., on the distribution of mass in it. For example, the centre of gravity of a uniform wire is at its mid-point.

What is a mass of a bus?

United States. The curb weights for these transit buses currently range between approximately 20,000 and 33,000 pounds, and fully-loaded weights range from approximately 30,000 to 44,000 pounds. As such, passengers comprise roughly one- third of the gross vehicle weight (GVW) of a fully-loaded 40-ft transit bus.

Why can you stand up on a bus?

When people get on the bus, the centre of gravity changes dependent on where they are. If most people are on the lower deck, then the centre of gravity remains low. As more people climb the stairs, the centre of gravity inches up with them. When a bus is stationary or going in a straight line, absolutely nothing.

Why can’t you stand on the upper deck of a bus?

In a double decker bus passengers in the upper deck are not allowed to travel standing, because if they stand the centre of gravity of the system of the bus and all the passengers shifts to some more height.It affects the stability whichn leads the bus with the passengers to fall down.

Why do double decker buses sway when turning?

The topdeck standing passenger will sway outwards when the double-decker will turn. (On a Left turn, the standing passenger will sway towards the Right side of the bus) This will cause the Centre of Gravity to move outwards (significantly more than the seated passenger) and away from the direction of the turn.

What happens to the center of gravity when a bus turns?

(On a Left turn, the standing passenger will sway towards the Right side of the bus) This will cause the Centre of Gravity to move outwards (significantly more than the seated passenger) and away from the direction of the turn. It will be moving away from the track-width of the double-decker.

What happens when a bus turns a corner?

When a bus is stationary or going in a straight line, absolutely nothing. When it comes to turning, that’s a whole other matter. A higher centre of gravity makes a vehicle more unstable. An unstable vehicle going around bends is a disaster waiting to happen; it could easily topple. A strong and stable bus turning a corner.
