工程力学是机械设计制造类专业(包括数控技术、模具设计与制造)必备的入门知识,与工程实际联系密切,因此,在教学中存在一定的难度,主要表现在理论知识比较多,直观抽象,记忆公式比较多,计算任务量大,而且技工学校学生数学、物理基础差,自觉性差,学习积极性不高,更增加了教师的教学困难。 Engineering mechanics is a necessary introductory knowledge of mechanical design and manufacturing specialty (including numerical control technology, mold design and manufacture), which is closely related to engineering practice. Therefore, there are some difficulties in teaching, mainly in the aspects of theoretical knowledge, intuitive abstraction , The memory formula is more, the computing task is large, and technical school students math, physical basis is poor, poor consciousness, learning enthusiasm is not high, but also adds to the teaching difficulties of teachers.
