Does anyone know of any websites that show examples and
basic formulas for things like figuring out deflection and the like?

www.ufl.edu

www.efunda.com (great site with online calculators but it's not 100% free)

those r helpful. Thanks guys.

Some of the people that know me are probably wondering what my non-work related links look like LOL

I tried the horsepower formula here as applied to our car and it's off by a
mile.

Is it low? Probably because the HP rating auto manufactures give is gross
(that's a motor on a stand) not net which is with the car and drive line
connected.

Regardless, this type of calculation is not very accurate to begin with,

Horsepower Results - 1/4 Mile Method

Your Mustang Cobra weighs about 3430 pounds and can complete a 1/4 mile in about 13.4 seconds. That means that you've got about 281.75 HP at the wheels, and about 366.28 HP at the flywheel.

Close, its a 320 HP engine.

"Your Mustang Cobra weighs"

enough with that filthy language...

I have no idea what any of this has to do with Inventor, but I can't help myself.
Hopefully I have enough brownie points built up that I won't be in too big of doo doo.
Hi Anne 8^)

Seemed pretty close to me. 8.6 seconds 2000 lbs 621.47 HP at the wheels, and about
807.92 HP at the flywheel.

That is about what I had always figured I had??

I know... lets bring this back around... What method do most people that have drawn
tube framed cars used in Inventor? Master sketch? Fixed workpoints and 3d sketches? or
surfaces to extract the 3d path or ??

They are assuming a set amount of loss through the drive train. There is
usually a very big difference between production cars and modified racers.
The numbers I got from putting in my numbers are a bit low (about 30 HP)
compared to my dyno results.

I haven't done any full blow car frames but I did do a go kart frame for a
friend. I used workpoints and 3D sketches as it was all tubular steel
construction.

That becomes a more drastic difference (obviously) when you are dealing with less HP. Here is what it came up with for my 74 HP (Thats bhp measured like the old days, no alternator/water pump/oil pump etc.) Spitfire:
Horsepower Results - 1/4 Mile Method
Your Triumph Spitfire Mk. III weighs about 1655 pounds and can complete a 1/4 mile in about 20.2 seconds. That means that you've got about 39.69 HP at the wheels, and about 51.59 HP at the flywheel.

I think the car actually weights a lot closer to 1500 lbs.

It was high, by about 500 HP! No kidding. Car weight 2350, ET. 6.75. 1470 HP
(flywheel) does the job nicely.
