Are there industrial gear-shifting gearboxes that can handle 5000 horsepower?
If so which ones? Can you please name a few and post some links if possible?
I asked because there are rumors of a 5000 hp supercar: The Devel Sixteen.
While most people think they are lying/pipedreaming about the...
I know they are nowhere near as hot or cold galvanizing, but
Are Zinc rich spray paints really better than regular paint in preventing corrosion?
Does it adhere firmly to bare metal (mild steel)?
What about using regular paint on top of Zinc rich paint?
Would it peel off?
Any other advice on...
Would riveted Titanium panels make chrome plated steel any more prone to corrode?
Which is better to use steel, stainless steel or Titanium rivets to avoid the chrome plated steel frame corroding?
I tried Googling it and found almost no info.
So far only found student exercises to use thermal expansion coefficients and formulas.
Does cooling a rivet before installing actually helps ensure a tight fit thus preventing it from coming loose?
Or does it actually adds stress when it expands?
Titanium sheets are going to be riveted to a rectangular steel tube frame.
Can Titanium sheets also be bonded, glued, brazed, soldered or welded to steel to add SOME additional strength to the strength from the rivets?
i.e. Titanium is said not to be weldable to steel.
Can it be done to create...
I've read somewhere that the semicircular (fishmouthed) welds in round tubes are much stronger than those straight line ones found in square tubes.
Is that true?
If so, Why? Aren't square tubes supposed to have more weld length? Does the curved weld shape helps?
Is there a big difference in...
If a mechanical device (consuming energy) is used to blow or suck air to reduce the vehicle aerodynamic drag
Can this energy consumed by the mechanical device be overcompensated by a lesser amount of energy required to move the car at the same speed?
Thus net energy savings
Is there a...
Any drawbacks or challenges from using 304 stainless steel tubes for a car spaceframe?
Some say stainless steel is brittle and will fatigue soon, while others say its not a big deal as Chrome-Moly is also somewhat brittle yet is has been used many times, even in aircraft.
Are SS 304 welds...
Bifacial solar cells can produce electricity from light coming from both sides.
Reportedly they produce up to 20% more electricity with diffuse sunlight coming from the back.
However their price is much more than 20% higher.
What about just using a separate solar cell on each side?
What cell...
Is there a distinct (and high) fatigue limit for stainless steel?
In other words Is there a fatigue limit force below which even millions of cycles wouldn't cause failure. Pretty much like Steel compared to Aluminum
Is there a big difference between Austenitic, Ferritic alloys?
If you could use the A-pillars (and/or the A-pillar tubes in a rollcage) to route hot radiator and engine area air to the roof
Where would you place the hot air exit?
Fore/aft: In the windshield header, roof midsection or backlight header
Side to side: roof edges or roof center.
What would be...
I'm confused on how to read solar cell efficiency vs wavelength charts
http://en.wikipedia.org/wiki/Quantum_efficiency
This chart suggests that external quantum efficiency is over 80% for wavelengths from about 500 to 1000 nm.
However this doesn't relate to real world efficiency because of...
Using the air flow already created by the fans to divide the airflow in two sections a straight inner section and a (curved) Venturi outer section that sucks out the boundary layer thru holes in the test section area.
Something like this
Would this array need extra flow straighteners?
Does...
Weren't cars or models supposed to occupy only a small fraction of the wind tunnel cross sectional area?
Yet in the A2 wind tunnel
http://www.a2wt.com/
cars use about 1/3 of the tunnel width and height
How do they avoid interference from the tunnel walls?
I read somewhere that they adjust the...
Are there some sensors submerged that can measure the approximate ethanol to gasoline ratio in the fuel tank?
So far I've only heard of exhaust sensors.
Is there a more direct way to measure this ratio?
Maybe some sensors still in R&D stage?
What the best design for it to absorb energy in a crash, pretty mucu like a crumple zone, while still having good torsional stiffness?
Something like this...
In the first image the read arrows pinpoint the aluminum crumple zones.
What would happen if you add some x-braces?
Depicted in red in the second image.
Also, do the holes drilled in the aluminum beams help deformation upon impact?
For a transverse engine, rear wheel drive bike or dragster.
A revving-up engine engine creates "counter-torque". Not sure if there's a technical name for it.
But it is the torque the engine exerts on its MOUNTS opposing the direction of rotation.
It can clearly be seen while revving-up the...
Where an external fixed (non rotating) disc brake caliper brakes or releases a (rotating) disc to shift gear?
As to be easily serviceable by just replacing the worn caliper pads.
In most planetary transmissions I know of, brakes are applied but both parts keep rotating together and are not kept...
