本书主要适用于高等学校本科应用型人才的培养需要。本书对传统的工科理论力学教材体系作了较大改革。静力学采用以动力学为基础的理论体系和新的内容编排。运动学加强解析法,在按课程基本要求讲授合成法之余,在全部运动学中贯穿解析法。动力学加强动力学普遍定理。考虑应用型本科学生的特点,讲透解题方法。采用新的体系和讲透解题方法,使理论力学比较容易学。
全书包括3篇16章,静力学篇:力系作用量,物体的受力分析,平衡力系作用下物体的受力;运动学篇:点的运动学,刚体的基本运动,刚体的平面运动,点的复合运动;动力学篇:质点动力学基本方程,动量定理,动量矩定理,动能定理,动静法,碰撞,虚位移原理,拉格朗日方程,振动。
本书包括理论力学多学时课程基本要求的内容,可作为高等学校本科机械、土建类等专业理论力学课程教材,也可供高职高专、成人高校师生及有关工程技术人员参考。
本书配有电子教案。
