Also how bullet proof is it? I know it is a titanium nickel alloy so I’m guessing it may be strong with the titanium in it.

Why do we need a flywheel in an automobile? Most people say that an engine produces power only in one stroke.so a flywheel is used to absorb a part of that energy during the power stroke and help the engine to get through the other three strokes.But why can't that energy be stored in the mass...

Is there any engine which works using electromagnet?

My name is Vivek And i have just joined this forum.I am mechanical engineering student but i have great interest in aerospace.I want to learn more and more about aerospace and mechanical.I can made simple aeromodelling projects side by side just to enhance my aerospace engineering knowledge.Hope...

< Mentor Note -- thread moved to HH from the technical physics forums, so no HH Template is shown > HEY guys ; I want to know the types of EARTHING done in automobile . Anybody having any idea ?

Hi all, I need to calculate the friction coefficient between road and the tyre of the car. I came across few answers like which solves as from the following torque equation. Engine torque = braking torque + acceleration troque + Inertial torque + drag torque + rolling resistance. For...

I have a question about the greenhouse effect that I hope you all can answer. My neighborhood went bonkers last night b/c an older woman left her dog in her car at 10:30 pm to do some grocery shopping. It was dark, but it was 84 degrees. I know this would be extremely dangerous if the...

So, I don't want to disclose why I want to know about this because its to do with a friends invention and it would be unfair to publish too much information without his consent. That's my disclosure so to speak. I'm interested in how static electricity is managed in vehicles. I remember...

barring a few exceptions i read that it is because they aren't effecient at small scale. can someone elaborate on that? also, would even smaller turbines need some time to start up?

Automobiles -- why not to remain in 1st gear? why not to remain in 1st gear ??

Homework Statement Hi, I'm hari. I'm doing final yr B.E. I'm trying to do the headlight automation in automobiles. bt i dono by which device i can do it efficiently?? in my project i wan to sense the light and if the amount of light exceeds the particular value the vehicle wants to dim the...

Some days ago my friend who lived in the US was telling me that he was thinking of buying a used Mercedes car. That car was in a very good condition. The price was around $3,500. It's so cheap when compared to Indian market. I think that automobiles' rates in the US are quite less as compared to...

Homework Statement At highway speeds, a particular automobile is capable of an acceleration of about 1.6 m/s2. At this rate, how long does it take to accelerate from 83 km/h to 101 km/h? Homework Equations a = Change in Velocity / Change in time The Attempt at a Solution How do...

What about using water as fuel in Automobiles, recently I've seen in local TV channel of our country, Genepax Co Ltd of Japan built a new car that uses water as fuel. The system produces Hydrogen from water. For more detail, I used this link, [crackpot link deleted] Welcome for More...

1. A sport car starting from rest can attain a speed of 60 mi/hr in 8s. A runner can do a 100-yd dash in 9.8s. Assume that the runner is moving with a constant speed and that the car starts at the instant he passes it. How far will both travel until the car overtakes the runner? (convert...

I'm on another forum debating the topic, and it's been quite a while since I've taken a physics course. Say, for whatever reason, the acceleration of gravity doubled. So now the vehicle would have twice the weight, but the same mass. How would that affect the acceleration of an automobile on...

Another terrific set of pictures by everyone involved. Well done! This will be another tough contest to vote on. 1. GeoMike http://www.mcschell.com/cog.jpg 2. larkspur http://home.comcast.net/~larkspur2020/soaring.JPG 3. Janus...
