UNIT 1: ENGINEERING - WHAT'S IT ALL ABOUT? 1. What is engineering? Engineering is a scientific field and job that involves taking out scientific understanding of the natural world and using it to invent, design and building things to solve problems and achieve practical goals. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. New vocabulary: Engineer(n) (N) Kỹ sư Achieve (v) Thực hiện Engineering (n) Kỹ thuật Discoveries (v) Khám phá Scientist(n) Nhà khoa học Instrumental(adj) Góp phần vào Inventor(n) Người phát minh Involve Liên quan Translate : ....................................................................................................................................................... ............................................................................................................................................................ ............................................................................................................................................................ ............................................................................................................................................................ ............................................................................................................................................................ ....................................................................................................................................................... What does an engineer do? Engineers design, evaluate, develop, test, modify, install, inspect and maintain a wide variety of products and systems. They also recommend and specify materials and processes, supervise manufacturing and construction, conduct failure analysis, provide consulting services and teach engineering courses in colleges and universities.

Multimeter: This instrument can be use to measure a number of different electrical quantities, such as voltage, current, and resistance, ..it is a combined voltmeter, ammeter, and ohmmeter. Multimeters can have analogue or digital displays and can be switched to different measuring ranges. Multimeter instrument measure ...................................................................................................................................... ...................................................................................................................................... ...................................................................................................................................... ................................................................................................................................... Logic probe This instrument is use for measuring voltage levels and pulses in digital logic circuits. When the probe is placed on the pin of a logic IC, small coloured leds light up to indicate if a pulse is detected or whether the pin is at a high or a low logic level. Logic probe ...................................................................................................................................... ...................................................................................................................................... ...................................................................................................................................... ................................................................................................................................... Oscilloscope This instrument is use to measure fast-moving signals. It shows how a signal varies with time or relative to another signal. It uses a cathode ray tube to display the wareform of the measured signal on a screen. Oscilloscope ...................................................................................................................................... ...................................................................................................................................... 16
...................................................................................................................................... ................................................................................................................................... Function generator This instrument contains a triangular wave oscillator which can be switched to produce triangular, square, or sine waves over a range of frequences. It is use to test and a adjust a variety of electronic equipment such as audio amplifiers. The function generator provides a know signal which can be injected into a circuit. Often it is used with an oscilloscope so that a visual display of the waveform can be seen. ...................................................................................................................................... ...................................................................................................................................... ...................................................................................................................................... Task 4: which of the instruments would you use to do the following? 1.to check a fuse 2. to determine the frequency response of an audio amplifier. 3. to test for presence of a control signal on the output pin of a computer chip. 4.

Cathode ray tube Televisions as well as computers, radar systems, and oscilloscopes use a cathode ray tube(CRT) to produce an output display. The construction and operation of the CRT is similar in it case but the simplest type of CRT is found in oscilloscopes. Televisions ...................................................................................................................................... ...................................................................................................................................... ...................................................................................................................................... A CRT is really a large vacuum tube valve. It has..1......... main sections. The first sections is an electron ..2.............which emits a stream of electrons. The electron gun contains an electron lens which...3.......the electrons into a narrow electron...4........... The second section is a..5.......system, which allows the beam to be moved..6....... or horizontally. Oscilloscopes use charged metal..7..........to give..8.......deflection, where as televiton sets use electromagnetic coils to give electromagnetic..9............... The last section is a screen with a ..10.........coating. The electron beam hits the screen, making the phosphor glow and causing a spot to be displayed. The colour of the spot depends on the type of phosphor used. 18
Language study: cause and effect, 2 Study these statements: 1. The electron beam hits the screen 2. The phosphor glows Why does the phosphor glow? What is the relationship between statement(1) and (2). Statement (1) is a cause and statement(2) is an effect. We can link scause and effect statements in a number of ways. Study these ways, which use cause and make. 1. The electron beam hits the screen causing The phosphor to glow 2. The electron beam hits the screen making The phosphor glow Now study these cause and effect statements: 3. The phosphor glows 4. A spot is displayed The effect is in the passive. We can link cause and effect like this: The phosphor glows causing a spot to be displayed Task 6: link each of these cause and effect statements to make one sentence 1.a a magnetic field is set up in the speaker coil. 1.b the coil vibrates. 2.a the coil pushes and pulls the speaker cone. 2.b sound waves are produced. 3.a a voltage is applied to a quartz crystal. 3.b the quartz crystal expands and contracts 4.a a voltage is applied to the Y –plates. 4.b the electron beam is deflected. 5.a current flows through the filament. 5.b the heater glows.
