Destroying Tornadoes

[Trekker4747]

I propose an experiment noknowes. Step 1: Drive a 1 ton truck at 55mph, use 1 joule of energy and press the brake and measure how long it takes you to stop the truck.

Step 2: Have a friend drive the same truck at the same speed straight at you. Hold your foot out and at the proper moment expend the same 1 joule of energy by moving your foot forward and pressing against the bumper of the truck. Have your friend report back with the happy results

The result of the experiment you ask? The average IQ level on the planet goes up.

Is that literally what he's arguing?

Is it really possible for someone to be that dumb? (Or to at the very least ignore things like hydraulics.)

 

[Australis]

^ Apparently so.

 

[Sparky]

Yep, its that dumb. His example for not needing terawatts of energy to stop a tornado was he could stop a vehicle by only expending a joule of energy to press the brake.

 

[Birdog]

Has he even seen a tornado?

 

[Silvercrest]

In "Night of the Twisters", I imagine.

This is what an F5 can do to a one ton pickup truck. Also note the surrounding landscape...

Will that be one Cerwin Vega or two?

Ya know, I bet the application of just a couple a joules of energy would'a stopped that truck from flyin' like that. Right noknowledge?

 

[Sparky]

It just needed some speakers and some brakes.


do.you.understand.now???????????"

 

[Trekker4747]

All I need to do is keep blowing out puffs of air opposite the direction of the tornado's direction of rotation! If I do this enough times the speed of my breath will counter act the speed of the tornado's spin! Viola, no more tornado!

 

[Silvercrest]

Yes, but it only works if you have enough hot air.

 

[Trekker4747]

Yes, but it only works if you have enough hot air.

If I blow right the air coming out of my mouth will be my body tempeature -98.6*-which is way hotter than the air around a tornado.

So, no problem!

 

[Silvercrest]

Not enough! You need the amount of hot air some other posters seem to possess.

 

[Alrik]

You may have hit upon something there. I think we finally have the answer on how it could be done.

 

[Silvercrest]

Then we should give noknowes some credit. Perhaps he does have the ability to wipe out a tornado.

That is not a valid picture.

The tornado did not do that directly.

WHAT HAPPENED WAS THE TORNADO PICKED IT UP AND THEN IT WAS DROPPED FROM A HEIGHT CAUSING THE DAMAGE.

It was not caused directly by the tornado but by an action of the tornado in picking it up and dropping it causing it to be smashed.

If a car travelling at 70 mpg suddenly had the fuel leak away then you are saying it would it would not stop.This is absurd.

Merely pushing the brake pedal stops the car regardless of fuel in the tank or not.EVERY MOTORIST WOULD AGREE WITH ME.

Our experiments confirm the validity of using controlled interference to modify tornado behaviour.


I can also reveal to you we have made an astonishing discovery accidently while doing these experiments.This discovery can have broad applications in the field of transport.

This discovery will be revealed to you shortly in a thread titled .....

[Silvercrest]

Oh, boy, an upcoming thread! More target practice!!!

You're confusing things.

Firstly, the big one, being that the energy it takes to stop your car isn't coming from the same place as the energy it took to get the car up to speed.

Your car got up to speed by taking gasoline from the tank, igniting it, using the detonation to move pistons, to move gears, to move axles, to move wheels. The energy being used to stop the car is not coming from fuel but from the friction between the brake pads and the brake rotors. Friction that is created in the car's hydraulic systems when you press the pedal.

Regardless, it takes the same ammount of energy to stop the car as it does to get it up to that speed. But both energies *have* to be the same. The very laws of physics demand it.

 

[chardman]

Front disc brakes typically require 1,000-1,200 psi of hydraulic pressure to fully actuate.

Wait!!!! Hydraulic pressure?!? Ya mean the pressure of my foot alone isn't what actually stops the vehicle? Pushing the brake pedal merely triggers a whole series of mechanical events, which unleash tremendous mechanical forces to bring a vehicle to a stop?!?

That's right my intellectually naive little buddy. And we're probably talking about even more power than you imagine, because a typical brake pad has a surface area of several square inches. So we need to multiply that 1000psi or so that we talked about earlier, times the surface area of the brake pad, times the number of disc brakes on the vehicle. Altogether we're talking about applying a minimum of several tons of mechanical force each and every time you apply the brakes to stop a moving vehicle.

It might not be a bad idea for you to go to a really basic science and technology site, such as http://www.howstuffworks.com/ and read up on Leverage, Hydraulics, and Friction.

I'd also recommend you visit http://www.physics4kids.com/ or any other site that can explain Newtonian Physics, in simple terms even you can understand.

 

[Trekker4747]

An automotive repair course wouldn't hurt either.

 

[FordSVT]

I propose an experiment.

First, he could have a friend step lightly on his finger. It shouldn't really hurt, they don't have to stamp on it, just push it.

Then, he could try sticking his finger between the brake pad and rotor of a friend's car and have them push on the brake peddle by the same amount and see what the result is.

Yes? No?
