课程名称：学习如何运用切线原则构造物体 课程概述：切线原则是技术制图或工程制图中的一个重要主题。作为一名中学生或任何高等院校的学生，您将掌握构造机器零件、手工工具以及其他通过圆、弧和直线的组合进行绘制的技术对象所需的技能。本课程的教学方法非常简单，您可以轻松学习该技能，并能在观看完教程视频后的作业中立即应用。对于热爱技术或工程制图的人来说，这是一门非常激动人心的课程。 要成功利用切线原则构造任何物体，您需要遵循以下四个简单步骤： 1. 确定并绘制您在给定问题中看到的所有中心线。 2. 识别您在给定问题中看到的所有圆，并根据所给直径小心构造它们。 3. 识别您在给定问题中看到的所有曲线，并利用切线原则，通过迭代方法仔细找到它们的起点和终点。 4. 确定给定问题中的所有直线，并小心构造它们，以切线方式连接其余的曲线和圆。 教程视频通过清晰简单的步骤演示了所有这些过程，即使是对切线原则知之甚少的人也能轻松理解。在舒适的环境中，您可以在几乎没有帮助的情况下实践所学内容。
Principles of Tangency is a topic in Technical or Engineering Drawing. As a student in a secondary school or any tertiary institution, you acquire the skills needed to construct such things as some machine parts, workshop hand tools, and other technical objects that are drawn by using a combination of circles, arcs, and straight lines.In this course, the method of teaching is so simple that you will learn the skill very easily with little or no aid; and you can apply it immediately on the assignment that is given to you at the end of the tutorial video. It is a very exciting course for those who are passionate about technical or engineering drawing.To successfully construct any object by using the Principles of Tangency, you will have to follow four simple steps. These steps are outlined as follows:1. Identify and draw all the center lines you can see in the given problem.2. Identify all the circles you see in the given problem and carefully construct them by using the given diameters 3. Identify all the curves you can see in the given problem, and by using the Principles of Tangency, carefully locate their starting points and ending points by iteration methods, ie. guessing them as illustrated in the tutorial. And lastly, 4. Identify all the straight lines that are in the given problem and carefully construct them to join the rest of the curves and circles tangentially.The tutorial videos demonstrate all these steps using clear and simple steps so that even the person who has little or no knowledge of the Principles of Tangency can easily understand it and at the comfort of his room, do what he or she was taught with little assistance.
