When some gun powder explode in a iron hollow cylinder , how much energy consume to destroy that cylinder?
We have inner and outer diameter and height .
I calculate all of energy by enthalpy of combustion , I don`t know how much convert to thermal energy and how much consume to destroy .
how much is the turk that a usual person enter over the bicycle pedal ? ( the range )
i want to know . is it enough to ride a bicycle through drastic uphill bye foot power? or use some booster to drive better . i want to design a hydraulic transmition for bicycle . do i have to use pressure...
