The center of gravity of a vehicle depends on all three weight distributions. Technically, it is the point where all the weight could be concentrated for purposes of calculating vehicle performance. More practically, it is an indication of how well the weight is distributed. Of the three weight distributions, the location of the center of gravity in the vertical direction is the most important because it affects stability - high is bad, low is good.
How do you find centre of gravity of a vehicle?
The higher the center of gravity the easier it is to roll over.
Yes, in a uniform gravitational field, the center of mass and the center of gravity coincide. This is because the force of gravity acts symmetrically on all parts of an object in a uniform field, resulting in the center of mass and center of gravity being in the same location.
To lower the center of gravity to improve handling and reduce the possibility of a roll over.
Should be about half way at the "belt-line"
It is best to keep the center of gravity low on any road vehicle. This can be done by design, and by loading the heaviest items lowest with lighter items higher up. So to answer your question, they need as low a center of gravity as is physically possible.
To reduce the centre of gravity and improve stability of the vehicle.
The center of gravity of the truck
No, the center of gravity of a lift truck shifts when it is loaded versus when it is unloaded. When a lift truck is loaded, the center of gravity moves higher and towards the front of the vehicle, which can affect its stability and handling. Drivers must be mindful of these changes to operate the lift truck safely.
Carrying heavy items can indeed cause an increase in a car's center of gravity. This is particularly true for SUVs, which typically have a higher center of gravity to begin with. To keep the center of gravity as low as possible, load heavy items as low in the chassis as possible, and towards the center of the vehicle. Heavy items should never be carried on a roof or luggage rack.
An object's center of gravity always lies at the point where its weight can be considered to act. For a symmetrical object like a sphere, the center of gravity is at its geometric center. In irregularly shaped objects, the center of gravity may not necessarily be located at the geometric center.
