What are important qualities to consider when designing a CO2?
Designing a CO2 Racer some combination of the two? If you’re in it for the speed, know that the following design factors have an enormous impact on performance: weight — the lighter, the better; aerodynamics — you want your car to cheat the wind; and rolling resistance — less is more!
What makes a c02 car fast?
Aerodynamics, thrust-to-weight ratio, surface drag, rolling resistance and friction–all play a role in what makes a CO2 car fast or slow.
How do you reduce drag on a CO2 car?
You can help reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body. Drag: Here’s where aerodynamics come into play. As an object moves through the air, it is met with air resistance as speeds increase.
How can aerodynamics be reduced?
You can reduce your vehicle’s aerodynamics by:
- Lifting it — “an inch of increased ride height degrades the coefficient of drag by about 10 drag counts [.
- Adding wider tires.
How do you reduce drag in water?
The solution? Keep your head and body under the surface as much as possible. There is surprisingly less wave drag under the water than on the surface because by keeping your entire body under water, you eliminate the surface from frontal drag.
How competitive swimmers are affected by drag?
Competitive swimmers competing in a race also can experience wave drag. Wave drag develops when a swimmer is moving quickly across the top of a body of water, creating waves. These waves cause imbalances in pressure on the body and can limit how fast a swimmer can move.
Why do swimmers push against water?
A swimmer push the water backwards to move forward because according to newton’s 3rd law of motion in each and every action there is an equal and opposite force so if he push water backwards then acc. to newton’s 3rd law he will move forward. To make the friction offered by water to push him forward.
What increases water resistance?
The water resistance increases by increasing the speed of the body through the water, and vice versa, The water resistance increases, by increasing the surface area of the body that moves through the water, and vice versa.
What is the fastest Olympic swim stroke?
freestyle
What is the most natural swim stroke?
How fast do Olympic swimmers swim 50m?
The Olympic Qualifying Time for the event is 22.01 seconds. Up to two swimmers per National Olympic Committee (NOC) can automatically qualify by swimming that time at an approved qualification event. The Olympic Selection Time is 22.67 seconds.
Who is the slowest swimmer in the world?
