Calculate center of gravity of eco marathon aka supermileage

In summary, the conversation discusses the need to find the center of gravity of a supermileage vehicle. The vehicle must meet specific dimensions, such as a maximum height of 100 cm, a maximum width of 130 cm, and a maximum weight of 140 kg without the driver. However, the calculation of the center of gravity requires more details about the distribution of mass, which are currently missing.

Hi, hope someone can help. I need to find the centre of gravity of a supermileage.
Here is the dimensions:

~The maximum height must be less than 100 cm.
~ The maximum height measured at the top of the Driver's compartment must be less than 1.25 times the maximum track width between the two outermost wheels.
~ The track width must be at least 50 cm, measured between the midpoints where the tyres touch the ground.
~ The wheelbase must be at least 100 cm.
~ The maximum total vehicle width must not exceed 130 cm.
~ The maximum total length must not exceed 350 cm.
~ The maximum vehicle weight, without the Driver, is 140 kg.

Hope anyone can help! Urgent

There's no answer unless you want to put all variables at their extreme limits, which you wouldn't. Also you need to know more details of mass distribution, in fact that's all you need, and it's also what's missing.
 

1. How do you calculate the center of gravity of an eco marathon car?

To calculate the center of gravity of an eco marathon car, you will need the weight of each individual component of the car. Then, using the formula CG = ∑(mi * xi) / ∑mi, where m is the mass of each component and x is the distance from the reference point to the center of gravity of each component, you can determine the overall center of gravity of the car.

2. What is the purpose of calculating the center of gravity of an eco marathon car?

The purpose of calculating the center of gravity of an eco marathon car is to determine the stability and handling of the car. A lower center of gravity typically results in better stability and handling, which can improve the overall performance of the car.

3. How does the center of gravity affect the fuel efficiency of an eco marathon car?

The position of the center of gravity can significantly impact the fuel efficiency of an eco marathon car. A higher center of gravity can make the car more prone to tipping, leading to increased drag and decreased fuel efficiency. A lower center of gravity can improve stability and reduce drag, resulting in better fuel efficiency.

4. Can the center of gravity of an eco marathon car be adjusted?

Yes, the center of gravity of an eco marathon car can be adjusted by changing the distribution of weight within the car. This can be done by moving components or adding weights in strategic locations to shift the center of gravity to a desired position.

5. Are there any safety concerns related to the center of gravity of an eco marathon car?

Yes, the center of gravity of an eco marathon car can impact its safety. A higher center of gravity can increase the risk of the car tipping over, especially during sharp turns. It is important to carefully calculate and adjust the center of gravity to ensure the safety of the driver and others on the track.
