Then they put the knife down, transfer(转移) the fork to their right hand,and only then do they transport the food to their mouth . This is clearly funny, but it is considered good manners.Tables are generally laid with one knife and two forks. The outside fork is for the salad. There is no need for foreign visitors to eat the salad with only a fork, but if you do use your knife, remember to save it for the meat course. Even desserts(except ice cream) are eaten with a fork and the spoon by your dessert is meant to be for coffee ( but if you use it for your dessert no one will say anything).( )46.______ eat almost everything with a fork.A.People in the USAB.

Funny Eating HabitsDWhen you want to see big cities in China , you can rent a car and drive in the cities by yourself. You can also take a taxi. But you will pay a lot of money for these two days. A lot of people like to go by subway or by bus. The subway is the fastest way to get around in busy cities even during the rush hour .It is now becoming more and more popular. You don’t need to pay much money if you want to take a bus, but it i s much slower than the subway. To see a city closely by bike is a cheaper and better way. But the best and wisest way to get around in downtown areas is to go on foot.根据短文内容判断正误。

A lever is balanced when the product of the effort force and its distance from the fulcrum is equal to the product of the load force and its distance from the fulcrum. If the effort force is 300 N and the load force is 1200 N, and the effort is applied 2 m from the fulcrum, calculate the distance from the fulcrum to the load.答案：Let the distance from the fulcrum to the load be\( x \). According to the principle of levers, \( 300 N\times 2 m = 1200 N \times x \). Solving for \( x \) gives\( x = \frac{300 N \times 2 m}{1200 N} = 0.5 m \).五、论述题11. Discuss the importance of mechanical vibrations in the context of machinery operation and maintenance.答案：Mechanical vibrations are crucial in machinery for several reasons. They can indicate the health of a machine, with abnormal vibrations often signaling a problem such as imbalance, misalignment, or wear. Monitoring vibrations can help in predictive maintenance, preventing breakdowns and extending the life of machinery.12. Explain the concept of stress concentration in mechanical components and its implications.答案：Stress concentration occurs in mechanical components where the stress is higher than the average stress due to geometrical discontinuities or material defects. This can lead to premature failure of the component under load, as the high-stress areas are more susceptible to fatigue and cracking. Designing to minimize stress concentrations and using materials with good fatigue resistance can mitigate these effects.。

Solutions are not only dependent regulations and political influence. As engineers we are empowered with the technical expertise to develop new and improved products and systems, but at the same time we must be increasingly aware of the impactof our actions on society and the environment in general and work conscientiously toward the best solution in view of all relevant factors.Design is the culmination of engineering educational process; it is the salient feature thatdistinguishes engineering design is found in the curriculum guidelines of the Accreditation Boardfor Engineering and Technology(ABET).ABET accredits curricula in engineering schools andderives its membership from the various engineering professional societies. Each accredited curriculum has a well-defined design component which falls within the ABET statement on design精品文档．精品文档read as follows.Engineering design is the process of devising a system, component, or process to meet desired needs. It is decision makingprocess(often iterative),in which the basic sciences, mathematics, and engineering sciences are applied to convert resourcesoptimally to meet a sated objectives and criteria, synthesis, analysis, construction ,testing, and evaluation. The engineeringdesign component of a curriculum must include most of the following features : development of student creativity, use ofopen-ended problem statement and use of modern design theory and methodology, formulation of design problem statementand specification, consideration of alternative solutions, feasibility considerations, production process, concurrent engineeringdesign, and detailed system descriptions. Further, it is essential to include a variety of realistic constraints such as economicfactors, safety, reliability, aesthetics, ethics, and social impact.31、what's the main meaning of message (1)?A) Engineering design is a systematic process B) materials engineer's main workC) mechanical engineer's has good idea D) electrical engineer' main duty32、In the author's opinion, the design process is very complex and should taken into account many factors, from themessage who should NOT join into the design team _______.A) environmentalists,B) sociologistsC) engineersD) Government officials33、From the message, we can know the meaning of words “ABET”(at line third paragraph) is _____.A) a set of accredits standardB) a kind of design methodC) a department of US government which responsible for engineering designD) A set of law34、It can be concluded from the passage that in the exercise and training of student, which character of the following isNOT included in the curriculum ______.A) creativityB) new materialC) ethicsD) economic factors35、The title of the message is ______.A) the roles of engineers in manufacturingB) the importance of mechanical designC) engineering designD) The process of machine designTEXT 2Working drawings are the complete set of standardized drawings specifying the manufacture and assembly of a productbased on its design. The complexity of the design determines the number and types of drawings. Working drawings may be onmore than one sheet and may contain written instructions called specifications.Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completelydescribe the parts, both visually and dimensionally;(b)show the parts in assembly;(3)identify all the parts; and (4)specifystandard parts. The graphics and text information must be sufficiently complete and accurate to manufacture and assemble theproduct without error.共5 页第 2 页精品文档．精品文档Generally, a complete set of Working drawings for an assembly includes:(1) Detail drawings of each nonstandard parts.(2) An assembly or subassembly drawing showing all the standard and nonstandard parts in a single drawing.(3) A bill of materials (BOM). (4) A title block.A detail drawing is a dimensioned, multiview drawing of a single part, describing the part's shape, size, material, and surface roughness, in sufficient detail for the part to be manufacturedbased on the drawing alone. Detail drawings are produced from design sketches or extracted from 3-D computer models. They adhere strictly to ANSI standards and the standard for the specific company, for dimensioning, assigning part numbers, notes, tolerances, etc. In an assembly, standard parts such as threaded fasteners and bearings are not drawn as details, but are shown in the assembly view. Standard parts are not drawn as details because they are normally purchased, not manufactured, for assembly.For large assemblies or assembled with large parts, details are drawn on multiple sheets, and a separate sheet is used for the assembly view. If the assembly is simple or the parts are small, detaildrawings for each part of an assembly can be placed on a single sheet.Multiple details on a sheet are usually drawn at the same scale. If different scales are used,they are clearly marked under each detail. Also, when more than one detail is placed on a sheet, the spacing between details is carefully planned, including leaving sufficient room for dimensions and notes.36. Based on the message, which of the follow is wrong?订A) standard parts needn't drawn as detailsB) for simple parts, sometimes needn't to draw the detail working drawingC) for large assemblies details may drawn on multiple sheetsD) If different scales used in a single sheet, they should clearly marked under each detail37.

Since, for most earthbound mechanical systems, the mass remains essentially constant with time,defining the accelerations as a function of time then also defines the dynamic forces as a function of time.Stresses, in turn, will be a function of both applied and inertial (ma) forces. Since engineering design ischarged with creating systems which will not fail during their expected service life, the goal is to keepstresses within acceptable limits for the materials chosen and the environmental conditions encountered. Thisobviously requires that all system forces be defined and kept within desired limits. In machinery, the largestforces encountered are often those due to the dynamics of the machine itself. These dynamic forces areproportional to acceleration, which brings us back to kinematics, the foundation of mechanical design. Verybasic and early decision in the design process involving kinematic principles can be crucial to the success ofany mechanical design; a design which has poor kinematics will prove troublesome and perform badly.Any mechanical system can be classified according to the number of degree of freedom (DOF) which itprocesses. The system's DOF is equal to the number of independent parameters which are needed touniquely define its position in space at any instant of time.A rigid body free to move within a reference frame will, in the general case, has complex motion, whichis a simultaneous combination of rotation and translation. In three-dimensional space, there may be rotationabout any axis and also simultaneous translation which can be resolved into components along three axes. Ina plane, or two-dimensional space, complex motion becomes a combination of simultaneous rotation aboutone axis (perpendicular to the plane) and also translation resolved into components along two axes in theplane41、Kinematics research focus on the following EXCEPT ______..A) accelerations B) forceC) positions, D) velocities42、From the passage that for the design engineer the first and most important is____A) the service life of a machine B) the materials chooseC) the degree of freedom D) kinematic principles43、An mechanical system has uniquely defined position in space at any instant of time that ___.A) It should has one DOFB) It should Has two DOFC) the DOF and the number of independent parameters should equalD) It should has any DOF as want44、which one of the following is NOT TRUE _______?.A) A rigid body free to move in three-dimensional space may rotation about any axisB) A rigid body free to move in three-dimensional space is a simultaneous combination of rotationand translationC) A rigid body free to move in three-dimensional space can be resolved into components alongthree axesD) A rigid body free to move in three-dimensional space may has complex motion45、The best title for this passage would be _______.A) kinematics B) dynamicsC) kinematics and dynamic D) the important of kinematics共5 页第 3 页精品文档．精品文档四、英译汉（共20分）1．将下列英语句子译成汉语（共5小题，每小题2分）A perfectly rigid or inextensible link can exist only as a textbook type of model of ）1（a real machine member.Foundations should ensure the machine's stiffness; shock absorption and isolation ）（2are secondary considerations.cyclical or spring a mechanical component such as a is subjected to repetitive Thus, (3)if large after a strength, of applications stress levels much lower than the ultimate it will fracture number of repetitions of this stress.Interchangeability means that identical parts must be interchangeable, i.e., able to replace each 4）（other, whether during assembly or subsequent maintenance work; without the need for any fitting operations.A gear can be gripped axially between a shoulder on the shaft and a spacer, with ）（5torque being transmitted through a key.分）、将下段英语翻译成汉语（102As we look around us we see a world full of “things”, machines, devices, tools, things that we 订have designed, built, and used; things made of wood, metals, ceramics, and plastics.
