    Ek vs engine power in cars and space

    Help me please:) (1) An idealized engine with constant torque curve means constant acceleration. So for example if there is no air resistance and no frictions and car is on fixed gear and at 3000Rpm it produces 50Hp so at 6000Rpm will produce 100Hp. So he doubles the speed , doubles power and...

    Torque&Drag in a drillpipe (Johancsik, 1984)

    Hi! Is anyone experienced With T&D calculations using above mentioned model: ? I have a trouble to understand what exactly F1 is and how to calculate it. I know it is an axial force, so it is drag? And once you calculate drag for one element, you use it as F1 to calculate drag in 2ns element...
