Hello friends, You can multiply the weight of the wheels by 3... Their kinetic energy of rotation will remain negligible compared to that of the vehicle. By correcting my calculations, that's around 20 Joules when multiplied by 000 (proportional to the mass). I remind you that the kinetic energy of...

Hi Leo, There is no error. We must not confuse the moment of inertia of a mass m placed at a distance r from the axis: Jpunctual = mr² with the moment of inertia of a homogeneous cylinder of mass m and radius r: Jcyl = mr²/2 For driving, I prefer the second case :P details: http://fr.w...

do you know how to pedal hard? if, yes, no need to replace oil

The civil war in France? Mouhahahaha...with a Star Ac CD or the Arthur DVD (help) as a freebee? Hi Christophe, Well I see that you are in good shape again this morning. The French are already fighting among themselves for a yes or a no... (demo, traffic of all kinds, football stadium,...

Good evening Christophe, You take the years which help your reasoning... 1995/2005 marks a significant surge in real estate. This is what happened over 25 years in the USA, and I take the curve of the American West, the most speculative. https://www.econologie.com/fichiers/partager/123292014042i...

Hello, The “colossal income” offered by real estate is a myth. Over long periods (>15 years) real estate roughly follows inflation (barely more in recent years in the Euro zone). The fact that one can earn income from real estate assets is also not scandalous. ...

3) For the big wanker, is it yours or was it in the report? It's in the report, but not stated that way. A mother provides home care for the elderly. For 30 years, she has earned 1500 Euros. His daughter, not thin and noticeably slumped on the table, complains about a cigarette...
