课程名称：掌握静力学 课程概述： 《掌握静力学》是力学领域中基础且重要的一门课程。在这门课程中，您将学习物体或结构在静态力作用下保持平衡的条件，即它们何时保持静止或以恒定速度移动。您还将学会如何计算反作用力以及结构内部所经历的力，从而能够为结构设计和尺寸规划打下基础，以确保结构的安全性和适用性。 本课程适合对多个工程学科感兴趣的学习者，包括土木工程、建筑学、机械工程和航空航天工程。此外，非工程学科的学习者也会发现本课程非常有用，例如关注挖掘现场稳定性的考古学家、对牙桥力学感兴趣的牙医，或是关注脊柱及髋关节或膝关节所受力的骨科医生。 课程内容主要通过轻板授课，Katafygiotis教授将使用彩色马克笔直接在板上书写和绘图，为您提供一次激动人心且互动的在线学习体验。 课程大纲： 1. **理解力和力矩**： 开始复习牛顿定律，介绍力和力矩的基本操作，并概述支配它们操作的向量代数。 2. **力的等效系统和静力平衡**： 研究作用于刚体上的力和偶的效果，并明确粒子、刚体及刚体组合的平衡条件。 3. **稳定性和静力确定性**： 讨论稳定性和静力确定性的重要概念，帮助学生理解常常在教材中未充分阐述的内容。 4. **桁架**： 介绍桁架的分析方法，包括节点法和截面法，以及用于分析桁架的计算机辅助方法。 5. **面积属性与惯性矩**： 学习如何使用几何属性（如面积和重心坐标）将分布载荷替换为等效集中载荷，并计算特定坐标轴的惯性矩。 6. **内部力图**： 重点分析框架和梁的内部力，并绘制轴向、剪切和弯矩图，使用工程师普遍采用的标记法。 7. **结构的静力分析**： 提供两个复杂框架的静力分析示例，学生能够应用前一模块所学，绘制复杂框架的内部力图。 通过课程的学习，您将能够掌握静力学的基本原理，为进一步的工程设计和分析奠定扎实的基础。
Name:Understanding Forces and Moments
Description:This module introduces the basic operations that learners need to know in order to solve statics problems, we will start by reviewing Newton’s Laws, then introduce Forces and Moments and provide an overview of the vector algebra that governs their operations.
Name:Equivalent Systems of Forces and Equilibrium
Description:We will study the effect of a system of forces and couples acting on a rigid body and will state the conditions of equilibrium for particles, rigid bodies and assemblies of rigid bodies. The number of independent number of equations that are necessary and sufficient for satisfying equilibrium will be clearly stated.
Name:Stability and Static Determinacy
Description:We will discuss the important notions of stability and static determinacy. These are concepts that often are not presented clearly enough in some of the textbooks, causing confusion to students.
Name:Trusses
Description:Trusses are in a sense the simplest structures to analyze, used widely in structures such as bridges, industrial roofs, and cranes. We are going to introduce two methods of analysis, namely the method of joints and the method of sections to determine the member internal forces. In addition, we will study a computer-aided method for analyzing trusses.
Name:Area properties and Moments of Inertia
Description:To be able to deal with more complicated structures and loading scenarios, we will learn how to replace a distributed loading with an equivalent concentrated one using its geometric properties, such as its area and centroid coordinates. We will also learn how to calculate moments of inertia about specific coordinate axes and how to calculate their corresponding values about another translated and rotated system of axes.
Name:Internal Force Diagrams
Description:We will get to the most important part, which is analyzing frames and beams to calculate their internal forces and to draw axial, shear and moment diagrams. Contrary to most textbook presentations, we will adopt a notation that is universally adopted by engineers when using moment diagrams.
Name:Static Analysis of a Structure
Description:In this module, learners will be presented two examples of complex frames for static analysis. Learners should be able to apply what they have learnt in the previous module, calculate and plot the internal force diagrams. By the end of this module. students will be able to correctly draw axial shear and bending moment diagrams of rather complicated frames.
Course Overview: https://www.youtube.com/watch?v=sdom7zBIfkE Statics is the most fundamental course in Mechanics. In this course, you will learn the conditions under which an object or a structure subjected to time-invariant (static) forces is in equilibrium - i.e. the conditions under which it remains stationary or moves with a constant velocity-. You will also learn how to calculate the reaction forces as well as the internal forces experienced throughout the structure so that later you can properly design and size the foundation and the members of the structure to assure the structure’s safety and serviceability. This course is suitable for learners with interest in different Engineering disciplines such as civil engineering, architecture, mechanical engineering, aerospace. Non engineering disciplines may also find the course very useful, from archaeologist who are concerned about the stability of their excavation sites to dentists interested in understanding the forces transmitted through dental bridges, to orthopedic surgeons concerned about the forces transmitted through the spine, or a hip or knee joint. The content will be primarily delivered using light board. Prof. Katafygiotis is going to write and sketch with color markers directly on the board while facing you. You will have an exciting and interactive learning experience online!
