静力学

课程介绍 Course Introduction

学分：3 | 先修课：微积分、物理（力学） | 学期：大二上

静力学是机械工程的基础力学课程，研究物体在力系作用下的平衡规律。内容包括力的合成与分解、力矩、力偶、受力分析、平面与空间力系的简化与平衡、桁架内力分析、摩擦以及重心与形心计算。通过本课程学习，学生将掌握刚体平衡的基本理论与方法，能够对工程结构进行受力分析，为后续材料力学、机械设计等课程奠定坚实基础。

Statics is a fundamental mechanics course studying the equilibrium of bodies under force systems. Topics include force composition and resolution, moments, couples, free-body diagrams, simplification and equilibrium of planar and spatial force systems, truss analysis, friction, and centroids. Students master rigid-body equilibrium theory and conduct force analysis of engineering structures, laying the foundation for mechanics of materials and machine design.

大作业 Final Project

作业标题：平面桁架结构受力分析

学生需选择一个工程实际桁架结构（如桥梁桁架、屋架或起重机臂架），绘制结构简图并完成受力分析。要求采用节点法和截面法计算各杆件内力，绘制轴力图，并校核关键杆件的强度。需提交完整计算书一份，包含受力分析图、计算过程和结果讨论。

Students select a real truss structure (bridge, roof truss, or crane arm), draw the schematic and complete force analysis. Using the method of joints and method of sections, calculate member forces, plot axial force diagrams, and check critical member strength. A complete calculation report with analysis diagrams and discussion is required.
