Hello everyone, Mr. Servilimit a pleasure to have it in the debate. On the calculation, it seems very ingenious, you when dividing RPM for 60 seconds, is calculating, although I understand, the revolutions that the crankshaft gives per second. Then my opinion is that you have to take into account the length of the race or distance remembered, because speed is distance traveled in a time. Also according to what I understand, the piston from PMS whose speed is approx zero (is detained), when the crankshaft broken, the piston accelerates, achieves its maximum speed and then be restless until it reaches at zero speed at PMI. For this reason when Ismael calculates the speed of the embol as it showed it above, I add that this calculation was an average speed between the point of greatest rapids of the piston (maximum speed) with those of zero motion upper dead point (PMS) or PMI (lower). With respect to the debate

, in my opinion it is one of the best ways that the human being has had, not only technical things but not value ... Democracy for all ... greetings cordials.
