How does aerodynamics affect fuel efficiency?
A vehicle which produces lesser aerodynamic drag is more fuel-efficient as it requires lesser power to accelerate it. This is because the lesser the aerodynamics, the more resistance is put on the vehicle due to the wind; causing the engine to work harder making the pistons go faster burning more gas/oil. Aerodynamics play a more important role as the speed of the vehicle increases as the drag in directly proportional to the square of the vehicle's velocity.
Why does the shape of an automobile body affect gasoline mileage?
The shape of the vehicle affects the amount of drag the vehicle produces. Drag being resistance to forward motion due to air mass resistance. The more air that vehicle has to move, the more drag it produces, and the less efficiently it will move.
Can you suggest me some major project on automobiles?
Increasing importance of good aerodynamics, especially in light of emergence of electric vehicles. For the same performance (acceleration / top speed), a lower drag car requires less power and therefore , fuel consumpsion is reduced. Vehicle drag (newtons) = air drag + rolling resistance (of wheels) rolling resistance is proportional to mass (crr * mass) air drag = velocity2 * drag coefficient velocity in metres per second
How does streamlining work?
it works from the wind the lower your vehicle, the faster it will go. and that is formed from the wind pushing over your vehicle. for example if you look at a formula 1 car it is very low which gives your car/vehicle more aerodynamics.
How does aerodynamics affect the speed of the vehicle?
It affects you because you're an idiot.
What are trivia about physical science?
Trivia are details, considerations or pieces of information that is of little importance or value. Examples of trivia about physical science - What is aerodynamics - able to move through air with little resistance as possible. What is resistance - force of friction on a vehicle as it moves What is an axle - a bar or shaft on which wheels turn
Is the Mazda 6 safe in rollover crashes?
The 2009 and 2010 Mazda 6 sedans both scored a perfect score of 5 stars on their NHTSA Rollover Resistance Ratings. The Rollover Resistance Rating is an estimate of your risk of rolling over if you have a single vehicle crash and test how “top-heavy” a vehicle is.
How does the size of a vehicle affect its speed?
Bigger people are usually heavier and therefore will need alot more power to achieve equivalent speeds of smaller lighter people. It is all to do with power to weight ratios and aerodynamics (wind resistance).
How will you reduce drag forces in your bottle rocket?
the aerodynamics of the bottle can be increased or the bottle can be smoothened on all the sides therby increasing the aerodynamics therby decreasing the drag of the vehicle
Is a small car better in high winds?
A car that has better aerodynamics will be better in the wind than say, a tall vehicle with less aerodynamics size not been a factor.
What is resistance to motion?
Mass (inertia), also friction forces (air or rolling resistance)
What are three main driveline components that are added to a rwd vehicle to make it a 4wd vehicle?
Three main components are a transfer case, front drive shaft, and a front differential.
