Solid Mechanics and Mechanical Engineering Objectives After learning this chapter, you should be able to do the following Differentiate between the different types of basic loading conditions. Understand the basic approach of the Finite Element Method(FEM)

Statics, Dynamics and Mechanical Engineering 1、 Introduction Mechanics Science which describes and predicts the conditions of rest or motion of bodies under the action of forces The field of Classical mechanics can be divided into three categories 1)Mechanics of Rigid Bodies

Mechanical Engineering as a Profession 1、 Introduction Scientists study the world as it is, engineers create the world that never has been What is engineering Engineering is the art of applying scientific and mathematical principles, experience, judgment, and common sense to create things that benefit people In other words, engineering is the process of producing a technical product or system to meet a specific need What engineers do Engineers: Turning Ideas into Reality

Here we'll discuss the basic idea behind an engine, and then go into detail about how all the pieces fit together and how to increase performance Internal Combustion Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. The four-stroke approach is also known as the otto cycle

MasterCAM8软件是美国CNCSoftWare.INC.所研制开发的CAD/CAM系统，是最经济有效率的全方位的软件系统。包括美国在内的各工业大国皆一致采用本系统，作为设计、加工制造的标准。 第一章 MsterCAM8 的基础知识 第二章 旋钮实例 第三章 咖啡壶实体造型实例 第四章 闹钟实例

一、填空: 1.车用内燃机根据其燃料不同分为()和()。 2.四冲程发动机每完成一个工作循环,曲轴旋转()周,进、排气门各开启()次,活塞在两止点间移动()次

我们最近走访了一家工厂,发现停用切削液带来的性能飞跃令人吃惊。这个发现纯属偶然。切削液的缺点 迫使人们把加工零件的生产定额转到干加工上。需要是发明之母,员工进行了试验以确定是否能保持有效 生产。结果他们发现对于切削液的投资不一定能有所回报 在过去的二十年里,使用切削液的经济性己经发生了戏剧性的变化

（1)“选择模具钢时什么是最重要的和最具有决定性意义的因素?” 成形方法一可从两种基本材料类型中选择。 A)热加工工具钢,它能承受模铸、锻造和挤压时的相对高的温度

近年来CAD是 CADCAM集成系统技术创新的主角。相比之下,CAM领域却显示出 不应有的沉寂。然而,随着信息化需求的不断增加,企业同样热切企盼CAM,希望技术创 新之风能吹进CAM领域,涌现出能够与CAD系统相匹配的、功能强大、更符合加工工程 化概念、易于普及的新一代CAM产品
