Thread: Supersonic

Tweet

I don't think there's much worry about the counterweights going supersonic. If we use a diameter of 8", then the circumference that the tip of a weight describes is 25". At 10,000 rpm's, the tip travels 250,000"/min. This equals 20,833 feet per minute, 3.945 miles per minute and 236 miles per hour. Since the speed of sound is 761.2 mph @ 15* Celcius @ sea level, the same crank would have to spin to 32,250 rpm's to reach mach 1.

Somehow I just don't think that is possible, but Scooter might prove us wrong.

I remember something about 4000 feet per second on the velocity of the pistons being a limiting factor after that is reached things break quickly.
I dunno?

Don't worry, we got the right guy on the job.
