ask me car related physics questions

[frictionfighter]

i thought there was. firefighters use centrifigul pumps, so i thought thats what that was.

[frictionfighter]

oh nevermind the object behaves as if it were in a non-acelerated situation. so there is no centrifugal force

[f8ldzz]

What is the relationship between friction, tire contact patch, and cornering?

[Craftsman]

Hahaha... Centrifugal and centrifical... Hahaha

this thread is rediculous... I so want to flam the guy who started this thread...

Does having Slotted and Drilled rotors makes you stop faster?

if an ae86 is drifting from north to south and the earth is the inertial frame, where does the coriolis effect occur, due east or due west?

the cornholio effect occurs when you need TP for your bunghole

When you have a 440lb/in spring (sorry I don't know the metric conversion) thats X amout tall and you cut it a given amout, what'sit's new rate? Sorry its a bit vauge, but I'm not sure of the height of my springs. Example: if the spring is 12 inches tall, and you cut off 1 inch, what's it's new rate?

hey he hasn't answered anything yet!

[malcolm]

appleseed... it's the same rate. Spring Rates don't change if you change the length of the spring.

It does, if you learn about spring design, you'll find that it does...

The spring rates change based on pitch, mean diameter, diameter of wire, angle, length, and materials. More can be found here

You're going to increase the spring constant by cutting the spring, I don't feel like doing the math so I'm not going to. But this is a reason you shouldn't cut your springs without swapping out your dampers. If you have cut springs, you'll have a spring constant that is much higher than your damping and you'll get an undamped system. This means your car will bounce up and down like no tomarrow...

PHYSICS IS PHUN!

I think that solid rotors actually stop better because you have more surface area than both. Surface area is the most important factor when it comes to brakes in my opinion.

I do know that drilled rotors are drilled to cool the rotors down quickly to prevent them from warping and being useless when hot...

Slotted rotors are done so to warm up the pads quickly from what I understand. I may be totally wrong on this one, but the friction and resistance that the brake pads com across when they go over the slots cause the pads to warm up faster to operating temperatures...

If I'm correct, F1 cars only have drilled brakes to help with cooling.

Now here's some interesting questions...

What part of the car slows down the car?

What part of the car accelerates the car?

What part of the tire supports the car?

lets say there is a RWD car and a FWD car. same horsepower, engine, driver, same everything except that the drivetrain layout.... which will be quicker to 60? how bout the 1/4 mile?

not good enough for an answer?

[SidewaysGts]

Craftsmans questions sort of have multiple answers
