3400*60*pi*D/Vs where Vs is the speed of sound in length per second in the surrounding media, and D is the D is the diameter in same units length of the path traveled by the weight.3400rpm -- going at full speed -- at what MACH is an unbalanced weight at the end travelling?
The terminals "slowly heating due to friction" sounds like the shaft might be stationary while the motor revolves around it. It's a clue of some sort, though.
How does one define "unbalanced weight at the end", though? End of what?
Not that I claim that I'll be able to solve this one, butIf a 3400rpm 3v motor is going at full speed with its terminals slowly heating up due to friction, at what MACH is an unbalanced weight at the end travelling??
THERE IS AN ANSWER
