The difficulty of the postgraduate entrance examination for engineering mechanics in Kunming University of Science and Technology is relative, and the specific difficulty will be affected by many factors, including the candidates' own ability, preparation time and methods. Generally speaking, the postgraduate entrance examination of engineering mechanics is relatively difficult, because the subject involves more basic knowledge of mathematics and physics, and it is necessary to understand and master the corresponding theories and methods of engineering mechanics.

Specifically, the difficulties of engineering mechanics postgraduate entrance examination include but are not limited to the following aspects:

1. The basic requirements of mathematics are high, and it is necessary to master advanced mathematics, linear algebra, probability theory and other mathematical knowledge, and be able to use it flexibly in the process of solving problems;

2. There are many requirements for basic knowledge of physics, such as mechanics, basic knowledge of mechanics, mechanics of materials, etc., and it is necessary to understand and master relevant theories and formulas;

3. There are many subjects involved in engineering mechanics, including statics, dynamics, structural mechanics, elasticity and so on. , need to be able to cope with different types of problems;

4. Time is tight, the examination time is limited, and more questions have to be answered in a limited time, which requires high time management and problem-solving speed.

In short, the postgraduate entrance examination for engineering mechanics is difficult, which requires candidates to have a solid foundation in mathematics and physics, as well as a deep understanding and mastery of the theory and methods of engineering mechanics. In order to better prepare for the exam, it is suggested that candidates arrange the preparation time reasonably, make a scientific preparation plan, systematically review and practice with related textbooks and problem sets, strengthen the understanding and memory of basic knowledge, and improve the ability and speed of solving problems.
