Working drawings are the complete set of standardized drawings specifying the man ufacture and assembly of a product based on its design. The complexity of the design dete rmines the number and types of drawings. W orking drawings may be on more than one sh eet and may contain written instructions call ed specifications.
Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completely desc ribe the parts, both visually and dimensionall y;(b)show the parts in assembly;(3)identify a ll the parts; and (4)specify standard parts. Th e graphics and text information must be suffi ciently complete and accurate to manufactur e and assemble the product without error.Ge nerally, a complete set of Working drawings for an assembly includes:
(1) Detail drawings of each nonstandard parts.
(2) An assembly or subassembly drawin
g showing all the standard and nonstandard p arts in a single drawing.
(3) A bill of materials (BOM).
(4) A title block.
A detail drawing is a dimensioned, mult iview drawing of a single part, describing th e part’
s shape, size, material, and surface roughnes s, in sufficient detail for the part to be manuf actured based on the drawing alone. Detail d rawings are produced from design sketches o r extracted from 3-D computer models. They adhere strictly to ANSI standards and the sta ndard for the specific company, for dimensio ning, assigning part numbers, notes, toleranc es, etc.
In an assembly, standard parts such as t hreaded fasteners and bearings are not drawn as details, butare shown in the assembly vie w. Standard parts are not drawn as details be cause they are normallypurchased, not manu factured, for assembly.
For large assemblies or assembled with large parts, details are drawn on multiple she ets, and a separate sheet is used for the asse mbly view. If the assembly is simple or the p arts are small, detail drawings for each part o f an assembly can be placed on a single sheet .
Multiple details on a sheet are usually d rawn at the same scale. If different scales are used, they are clearly marked under each det ail. Also, when more than one detail is place d on a sheet, the spacing between details is c arefully planned, including leaving sufficient room for dimensions and notes.
31. Based on the message, which of the follow is wrong ?
A) standard parts needn’
t drawn as details
B) for simple parts, sometimes needn’t to draw the detail working drawing
C) for large assemblies details may dra wn on multiple sheets
D) If different scales used in a single sh eet, they should clearly marked under each d etail
32. Working drawings for an assembly MAY NOT includes: ?
A) BOM B) title bloc k
C) An assembly or subassembly drawi ng
D) Detail drawings of all parts.
33. For detail drawing, Which one of th
e following statement is not true ?
A) should not has different scales
er
models.
ltiview drawing of a single part
D) should Adhere strictly to ANSI stan dards
34. From the message we can infer AN SI is______?
A) a set of law B) a set of notificati on
C) an Organization D) IEEE governm ent
35. The topic of the message is______ ?
A) How to design working drawings.
B) working drawing’
s character and the key influence of how to d raw a working drawing
C) In the design process, what should b e considered?
D) What is working drawing

1.A gear can be gripped axially between
a shoulder on the shaft and a spacer, with
torque being transmitted through a key.
译文：
2.One or more members such as gears, sprockets, pulleys, and cams are usually atta ched to the shaft by means of pins, keys, spli nes, snap rings, and other devices.

Exercise 2 一、阅读理解（20points ）: Passage one The circuit element used to model the current-resisting behavior of a material is the ① . It is the simplest ② element. George Simon Ohm is credited with formulating the ③ relationship for a resistor based on experiments performed in 1826. This relationship is known as Ohm's Law. Ohm's Law states that the voltage across a resistor is ④ the current flowing through the resistor. The constant of proportionality is the resistance value of the resistor in ohms. The circuit symbol for the resistor is shown in Fig.1. For the current and voltage shown, Ohm's Law is u(t) = Ri(t) (1) where R≥0 is the resistance in ohms. Since R is constant, Eq.(1) is the equation of a straight line. For this reason, the resistor is called a linear resistor. A graph of u(t) versus i(t) for a linear resistor is a line passing through the origin with a slope of R. Resistors whose resistances do not remain constant for different terminal current are known as ⑤ resistors. For such a resistor, the resistance is a function of the current flowing in the device. In reality, all practical resistors are nonlinear because the electrical characteristics of all conductors are affected by environmental factors such as temperature. Many materials, however, closely approximate an ideal linear resistor over a desired operating region. Choose the best answer into the blanks. 1 A. capacitor B. inductor u (t ) i (t ) + _ Fig.1

1.1.1 We consider the flow of electric charges. A unique feature of electric charge or electricity is the fact that it is mobile; that is, it can be transferred from one place to another, where it can be converted to another form of energy. 我们认为电荷是流动的。电荷和电的特点是它具有流动性；即它可以从一个地方转移到另一个地方，在转移的过程中，电荷或电能转变为另一种形式的能量。 1.1.2 The power absorbed or supplied by an element is the product of the voltage across the element and the current through it. 一个元件吸收或者发出的功率是元件两端的电压和通过该元件的电流的乘积。 1.2.1 We might observe at this point that the polarity marks on Fig.1-4(b) are redundant since the polarity could be defined by the positions of the longer and shorter lines. 大家或许注意到图1-4(b)所标注的极性是多余的。因为恒压源的极性可以用长线、短线来定义。 1.2.2 It should be noted that an ideal voltage source (dependent or independent) will produce any current required to ensure that the terminal voltage is as stated, whereas an ideal current source will produce the necessary voltage to ensure the stated current flow. 应该注意一个理想电压源，(独立和受控)可向电路提供任意电流，以保证其端电压为规定值，而理想电流源，可向电路提供任意电压以保证其规定电流。 1.4.1 Still anther class of relationship is one between several variables of the same type which occurs as the result of the network configuration, i.e., the manner in which the various element of the network are interconnected. 另一类关系由于网络结构，即网络的不同元件互相连接的方式所产生的相同形式的一些变量间的关系。 1.4.2 Kirchhoff’s Current Law is based on the law of conservation of charge, which requires that the algebraic sum of charges within a system can not change. 基尔霍夫电流定律基于电荷守恒定律，要求一个系统内电荷的代数和不变。 1.5.1 Since a voltage is defined as existing between two nodes, it is convenient to select one node in the network to be a reference node or datum node and then associate a voltage or a potential with each of the other nodes. 由于电压定义为两个节点之间的相对变量，一个方便的做法是选择网络中的一个节点作为参考节点或基准节点，从而确定其他所有节点的电压和电位。 1.5.2 Mesh analysis is not quite as general as nodal analysis because it is only applicable to a circuit is planar. 由于网孔分析法仅适用于平面电路，故网孔分析法不像节点分析法那样通用。 1.6.1 We can proceed to our simplification of sinusoidal steady-state analysis by establishing the relationship between the phasor voltage and phasor current for each of the three passive elements. 通过建立三种无源元件各自的电压相量和电流相量之间的关系，我们可以对正弦稳态分析进行简化。 1.6.2 On the other hand, delta-connected sources are not common in practice because of the circulating current that will result in the delta-mesh if the three-phase voltage are slightly unbalanced. 另一方面，实际中三角形连接的电源并不常用，因为三相电压稍有不平衡就会在三角形连接的网孔中产生循环电流。 2.1.1 In every aspect of our increasingly technological society ---whether it is science,
