Yeah that's what I did.. I'm doing this in an ode solver in MATLAB so obviously my code is wrong elsewhere. thanks!

Hey guys, Just a simple question to see if I'm going insane. So say I have an expression for: \frac{dxy}{dt} and an expression for \frac{dy}{dt} , how to I go about isolating an expression for just \frac{dx}{dt} I have tried using the product rule but it doesn't work for what I want. I know...

Ok, I see. Why is voltage below rated voltage the same as operating it above the rated current? Is there anyway of quantifying battery losses beyond P=I^{2}*R? Thanks!

Hi, I am trying to figure out how Li-Ion batteries operate in regards to efficiency. I understand they have rated voltage and current etc. and to operate them at these parameters if possible. However, I'm wondering is it simply the current that has effect on their efficiency. By Efficiency I...

Hi, I'm attempting to make a model of a DC motor capable of calculating the efficiency of the motor for different values for torque. I have managed to make a code to generate the torque-speed-power plots for given inputs, however I have been unable to figure out how to calculate the...

Looks good, will give that a go. Thank you..

I suppose I could do that. It's just I'm running it in MATLAB in respect to time (using a loop). So say I want to graph the output velocity at the end, it would be handy to have something that would give me a constant velocity after a certain number of iterations of the loop..

Not very precisely at all. Just using basic equation of motions at a constant acceleration. I'm at a very basic level of the model so far and my brain isn't really working today. Basically, I'm trying to find a way to model the power output with respect to time incorporating both the...

Hi there, I'm trying to create a computer model which takes into account output power in a car due to acceleration, drag and rolling resistance. The car will be accelerating for a set amount of time and I am able to model the power required for this with respect to time, as well as the power...

I'm actually making a model of the proposed car to maximise fuel efficiency (km/kWh) so there's no way of doing any physical tension. I was under the impression that the total static friction was the maximum torque that could be applied to the car without it the wheels slipping?

Hi, I'm designing a propulsion system for an electric car as a part of a college project. I'm trying to find the minimum torque needed so the car can begin to move, I'm assuming this will be the greatest torque required for motor selection, provided the vehicle will accelerate relatively...
