Why do you need math to be a mechanical engineer?
Engineering is a purely math field! From the very basic engineering courses, all you do is math. You must compute things like trajectories of objects spinning, flying, falling, etc, or what an object might do if it were to start moving. You also need to compute areas and volumes of odd-shaped objects to more accurately represent them in problems to determine how they will move–crucial for mechanical engineers. Basically, if you’re not good at math, engineering is not the field for you.
