The "hurdle" of technical mechanics

Engineering mechanics is the first engineering course to combine mathematics and physical processes with a technical background. As engineers, we have to represent reality with equations so that, for example, component behavior can be predicted. This connection leads to difficulties for some students, either because they lack the basic knowledge of school mathematics (preliminary courses are offered for this) or because the interpretation of the derived equations, which then have physical significance, requires a capacity for abstraction. In addition, there are necessary mathematical aids that go beyond school mathematics (e.g. vector calculus, derivation and solution of ordinary differential equations, matrix calculus), but these are all provided.

Mechanics is structured axiomatically, i.e. apart from very few basic equations, all further relationships are derived from them. In this sense, the lectures are clearly structured and the relationships do not fall from the sky. This is different with experience-based lectures, where it is more about taking on board the experience and applying it in daily practice.
Your attitude to work will determine whether technical mechanics is a hurdle for you. We expect you to engage with the subject matter, i.e. that you also deal with the derivation of equations that are necessary for basic understanding. Unfortunately, it turns out that people are more inclined to memorize equations. However, simply memorizing equations does not make sense because engineers need to understand the equations when they are faced with new problems, which they do every day in their working life. Questions such as "Where can I apply these at all? Can I derive new mathematical relationships for new problems?" should not cause any difficulties.

And here we come to the real problem. You are now studying. Studying means: "academic learning and research at universities" (Latin: studere: "(to) strive for something, to make an effort"). This implies studying the subject matter intensively, acquiring and reading literature, solving problems, discussing questions with fellow students or lecturers and answering them together. And this means making an effort. It is easier if you motivate each other.
