User:Average/Avoiding Sudden Dematerialization
STUB i haven't tested these figures, these are rough estimates and my calculations might be off...
1 tsp of highly atomized (million parts/inch3), high octane fuel mixed 1:1 with oxygen in a 1dm3 (1000cc) ignites at about 100mph(?) and creates a force of about 60 lbs. On a 4-stroke engine, 2 rotations of the crankshaft per cycle and with 4 cylinders (=4 liters), that's 120lbs of torgue per revolution. At 5000 rpm that's equal to 120lbs x 5000rpm = 600,000rpm-lbs of torque. Now that's no measure anyone understands, so convert that to ft-lbs/minute. A 3" crankshaft has 3"xpi (remember that geometry in high school?) inches of rotation which equals 0.785 ft. So that 600k rpm-lbs converts like so:
600k (0.785ft/min)*lbs ~= 471k ft-lbs/min = (/60s) 7854 ft-lbs/sec = (/2000lbs) 3.9tons/sec. Since your car's less than 2 tons, that'll be enough to pull your car forward and accelerate quite nicely (there's another calculation to figure out that) until you reach your max-speed (and air friction slows you down), but think about the force: greater than 471000 ft-lbs (or 235 tons) of force each minute at 5,000rpm.
That amount of force is being harnessed in your engine each minute and being transferred to your crankshaft output. If you don't design your engine right, you will blow up.
Also, that steering wheel. Little bits of movement in either direction are harmless at 10mph, but when you get to 200mph, those little angular displacements of your wheels amount to 10 ft of motion (left or right) within about 1 sec. (check calculation). That'll wind you up in the other lane before you know it. You'll need some kind of variable steering gear that compensates for speed. Perhaps, hydraulic steering.
