Homework Statement
I have an assignment to calculate the temperature, T1, after combustion in a cylinder. The combustion itself happens at constant pressure. I also know the average molar mass, M, of the gases after combustion and that the specific heat capacity is constant and can be...
Homework Statement
The problem is to calculate the mean molar mass of the reaktion below, which takes place in a combustion engine.
C4H10 + z(0.79N2 + 0.21O2) → αH2O + βCO2 + γN2
where the molar masses for the different molecules/atoms are:
MH2O = 18, MCO2 = 44, MN2 = 28, MO2 = 32, MC =...
I'm not sure I'm following. If the new h is the old h plus x, then I can perform the calculations twice and the second time just add x to h? Or how would the equation look like?
Okey, so you mean that h in mgh is the length of the cable plus x, i.e. h ist the distance from the point of release to where it comes to a stop? If I can't neglect that, how should I do the calculations then? Since x depends on h, which depends in x?
Hi,
I'm designing a crane that is supposed to withstand forces due to a falling object attached to the crane with a non-elastic cable. I have some troubles to calculate what force that will be due to the falling object.
I figured that one way is to simplify this system with a spring with...
