Thankyou for your reply's. So the drag equation is D = Cd x ((P x V^2)/2) x A With V^2 (Velocity squared) do take the sum of the wind speed and carriage speed? i.e. if wind and carriage are same direction, addition, and if in opposite directions, subtraction? The weight of the carriage...

Hi All, I have a problem in which I am trying to calculate the force of the windspeed, x, on a surface area of a moving object, y. I am applying this to a monorail model, where a monorail carriage (lets for this purpose assume its a rectangular box) with a surface area on one side is y, is...
