Hi, Im not an electrical engineer, not even close to one, but I have been asked to design a terminal for a motor. I have the power (current and voltage) requirements so I need to work out what area of copper in the terminal will handle this power. Can anyone give me the equation, or point...

So can it be said that: Overall power = Motor Output Power - (Friction [X]) x V)

Hi. I was wondering if someone could help me out. I am trying to work out what a value of friction will do to the power of a motor. For example, if I know the power output of the motor is 1W, and I introduce X amount of friction, what will the resulting output in power be. Could someone...

Hi, First off, I am not doing a course in physics or maths so excuse me if this is a very basic question. I have the following equation (see attached) and I am trying to make dx the focus, ie: dx = XYZ Would anyone mind taking the time to help me do this? Regards, James

Hi. Im trying to measure the efficiency of a heat engine. I therefore need to work out what the input energy is to the heat engine. I have two problems. Firstly, how should I measure the heat going into the stirling rather than the heat coming out of the heater. Is it ok to measure the...

Hi. I was wondering if anyone had ever done a relationship analysis of compression ratio in relationship to efficiency. I have heard that higher compression ratio can often relate to efficiency, but I was hoping to find some kind of graph correlation on it, however I haven't been able to find...
