Basic Concept in MechanicsThe branch of scientific analysis which deals with motions , time , and forces is called mechanics and is made up of two parts , statics and dynamics , Statics deals with the analysis of stationary systems , i.e. , those in which time is not a factor , and dynamics deals with systems which change with time .对运动、时间和作用力做出科学分析的分支称为力学。

它由静力学和动力学两部分组成。

静力学对静止系统进行分析,即在其中不考虑时间这个因素,动力学对随时间而变化的系统进行分析。

When a number of bodies are connected together to form a group or system , the forces of action and reaction between any two of the connecting bodies are called constraint forces . These forces constrain the bodies to behave in a specific manner . Forces external to this system of bodies are called applied forces .当一些物体连接在一起形成一个组合体或者系统时,任何两个相连接的物体之间的作用力和反作用力被称为约束力。

这些力约束着各个物体,使其处于特定的状态。

从外部施加到这个物体的系统的力被称为外力。

Efficiency
Mechanical Efficiency is the ratio of work input to work output. It is often expressed as a percentage. The efficiency of an ideal machine is 100 % but an actual machine's efficiency will always be less than 100% because of the Second law of thermodynamics which states that the quality of energy will decay, eventually becoming heat. This means that some of the work put into the system is transformed (lost) into thermal energy (heat). In a mechanical system, friction is the most common cause of the work lost to heat.
A baseball pitcher does positive work on the ball by transferring energy into it .

3. Auxiliary views An auxiliary view is an orthographic view that is projected into any plane other than one of the six principal views. These views are typically used when an object contains some sort of inclined plane.
Describe details of a part
Assembly drawings
Describe the shape of a machine
Drawings convey the following critical information: Geometry – the shape of the object; represented as views; how the object will look when it is viewed from various angles, such as front, top, side, etc. Dimensions – the size of the object is captured in accepted units. Tolerances – the allowable variations for each dimension. Material – represents what the item is made of.

For industrial purposes, materials are divided into engineering materials or nonengineering materials. Engineering materials are those used in manufacture and become parts of products. 就工业效用而言,材料被分为工程材料和非工 程材料。那些用于加工制造并成为产品组成部分的 就是工程材料。

计算机集成制造业包含许多先进的技术,如:计 算机数字控制、计算机辅助设计、计算机辅助制 造业、机器人技术和实时控制,它甚至是一种新 的技术或新概念。

If we accept the fact that mechanical systems optimally coupled with electronics components will be the wave of the future, then we must also understand that the ripple effect (连锁反 应)will be felt all the way back to the university, where we now keep the two disciplines of mechanics and electronics separated and allow them to meet only in occasional overview sessions(学期).

You could work in research and development, product design, manufacturing, or projectmanagement. Mechanical engineers are in demand in almost every industry, ensuring a stable and rewarding career path.Section 4: University CoursesTo become a mechanical engineer, it is essential to pursue a degree in mechanical engineering from a reputable university. The curriculum typically includes courses in engineering principles, materials science, thermodynamics, fluid mechanics, and mechanical design. Additionally, practical training through internships or cooperative education programs is crucial for gaining hands-on experience.Section 5: ConclusionMechanical engineering offers a challenging and rewarding career for those with a passion for solving problems and a desire to create innovative solutions. With the right education and skills, you can embark on a successful journey in the field of mechanical engineering. Remember, the possibilities are endless in this ever-evolving discipline.第二课:机械设计基础Fundamentals of Mechanical DesignSection 1: IntroductionIn this lesson, we will explore the fundamentals of mechanical design. Mechanical design involves the creation and development of physical systems and components that meet specific requirements and specifications. This processrequires a deep understanding of materials, mechanics, and engineering principles.Section 2: Design ProcessThe design process typically follows a systematic approach that includes several stages. These stages include problem identification, conceptual design, detailed design, manufacturing, and testing. Each stage involves various activities such as brainstorming, prototyping, and evaluation.Section 3: Design ConsiderationsDuring the design process, there are several important considerations to keep in mind. These include functionality, efficiency, reliability, safety, and cost-effectiveness. It is also crucial to consider the environmental impact and sustainability of the design.Section 4: Tools and SoftwareTo aid in the design process, engineers use various tools and software. Computer-aided design (CAD) software allows for precise modeling and simulation of mechanical systems. Finite element analysis (FEA) software helps in analyzing the structural integrity and performance of designs.Section 5: Case StudyTo further understand the application of mechanical design principles, we will examine a case study. This real-world example will demonstrate how the design process isimplemented to solve a specific problem and achieve desired outcomes.Section 6: ConclusionMechanical design is a critical aspect of mechanical engineering. It requires a combination of creativity, technical knowledge, and attention to detail. By mastering the fundamentals of mechanical design, you will be well-equippedto tackle complex challenges and contribute to the development of innovative solutions.以上是《机械工程专业英语教程》的课文翻译。

Text & Translation
Mechanical design should be considered to be an opportunity to use innovative talents to envision a design of a product, to analyze the system and then make sound judgments on how the product is to be manufactured. It is important to understand the fundamentals of engineering rather than memorize mere facts and equations. There are no facts or equations which alone can be used to provide all the correct decisions required to produce a good design. On the other hand, any calculations made must be done with the utmost cle, if a decimal point is misplaced, an otherwise acceptable design may not function.
Text & Translation
People who perform the various functions of mechanical design are typically called designers, or design engineers. Mechanical design is basically a creative activity. However, in addition to being innovative, a design engineer must also have a solid background in the areas of mechanical drawing, kinematics, dynamics, materials engineering, strength of materials and manufacturing processes.

再者,专业英语对听说读写译的侧重点不同,其主要要求在于“读”和“译”,也就是通过大量的阅读对外文资料进行正确的理解和翻译,在读和译的基础上,对听、说、写进行必要的训练。 此外,专业外文资料由于涉及科技内容而往往极为复杂难以理解,加之这类文章的篇幅通常很长,所以只有经过一定的专业外语训练,才能完成从基础英语到专业英语的过渡,达到英语学以致用的最终目的。

作为工程技术人员,阅读专业英语文献的目的是理解掌握文献所叙述的理论或方法,以便在科研或生产实践中实施这些理论方法,或是进一步发展改进这些理论方法。
为了达到这些目的,首先要准确地理解原文。另一方面科技文献的写作特点是严谨,简洁。在论述理论和方法时一般都只给出重要的步骤。对有关的基础知识一般不详细阐述,也不给出公式的详细推导过程。

其次,英语科技文章在结构上也具有很多自身的特点,如长句多,被动语态多,大量的名词化结构等,这都给对英文原文的理解和翻译带来了基础英语中很难解决的困难。
