Conversely, as long as you are an engineering major, you will learn these three mechanics. After all, mechanics is the foundation of engineering. If you are not good at math, it will be a little hard to learn mechanics, but as long as you are serious, college mechanics starts from the most basic, so there should be no problem.
If you want to choose a major, it is recommended to choose the former. But now there are few jobs that can match the major after graduating from college. For example, my classmate studied tunnels in college, and now he is asked to be a bridge after work. Moreover, the work done after graduation is relatively not very technical, not to mention whether it will use mathematical theory. So don't have too much pressure to choose a major here. This will not determine your future. Successful people never talk about which major they have studied is decisive for them.
Good luck and happy enrollment.
