reliability‚ solar energy‚ and technological impacts to society. MECHANICAL ENGINEERS study the behavior of materials when forces are applied to them‚ such as the motion of solids‚ liquids‚ gases and heating and cooling of object and machines. Using these basic building blocks‚ engineers design space vehicles‚ computers power plants‚ intelligence machines and robots‚ automobiles‚ trains‚ airplanes‚ furnaces‚ and air conditioners. Mechanical engineers work on the jet engine design‚ submarines‚ hot air

familiarization of electrical apparatus. Name Image Symbol Uses of functions Galvanometer A galvanometer is a very sensitive meter which is used to measure tiny currents‚ usually 1mA or less. Ammeter An ammeter is used to measure current. Voltmeter A voltmeter is used to measure voltage. Resistor (Fixed and Variable) Fixed Variable A resistor restricts the flow of current‚ for example to limit the current passing through an LED. A resistor is used with a capacitor in

ELECTRICAL CONDUCTORS A conductor is an object or type of material which permits the flow of electric charges in one or more directions. For example‚ a wire is an electrical conductor that can carry electricity along its length. Physics All conductors contain electrical charges‚ which will move when an electric potential difference (measured in volts) is applied across separate points on the material. This flow of charge (measured in amperes) is what is meant by electric current. In most

It is very obvious from the comments posted in this thread that the people driving the use of the RaspberryPi as a PLC training tool have not conducted any professional‚ electrical and electronic engineering research into the design criteria required for an educational PLC or are prepared to acknowledge the legally required European Union safety compliance to IEC61508 and IEC 611313. A PLC’s functional criterion is an industrial control device used to automate electrically driven machinery

Changing Gender Roles in Our Society: Women’s Education and Employment Education and employment go hand in hand now a day in order to become financially successful in life. These are two unmistakably major parts of society today. In order to become successful a good job is needed‚ and in order to get the job a good education is needed as well. But women especially need to emphasize more in these two subjects than men; due to past gender discrimination which brought on Equal Employment Opportunity

Electrical Cable Cross section is just a two-dimensional view of a slice through an object. An often asked question: How can you convert the diameter of a round wire d to the circle cross section surface or the cross-section area A (slice plane) to the cable diameter d? Resistance varies inversely with the cross-sectional area of a wire. | ------------------------------------------------- Top of Form | Wire diameter d | unit | | | Cross-sectional area A | unit2 | | |

Introduction This experiment tests electrical conduction. Electrical conduction is the transportation of an electrical charge through a substance. This is done by the electrical charge/current being sent through the substance via electrons. These electrons carry the electrical current/charge throughout the substance’s length until another conductor is able to receive the electrons charge. Part B: Risk Assessment: During the construction of “the modified hurler‚ “

PIPER JEFFREY DEVOLDER Jones Electrical Distribution After several years of rapid growth‚ in the spring of 2007 Jones Electrical Distribution anticipated a further substantial increase in sales. Despite good profits‚ the company had experienced a shortage of cash and had found it necessary to increase its borrowing from Metropolitan Bank—a local onebranch bank—to $250‚000 in 2006. The maximum loan that Metropolitan would make to any one borrower was $250‚000

Electrical Charges: Electrical charges come as plus or minus. Like charges repel‚ unlike charges attract. Electrons and protons have‚ to fantastic accuracy‚ equal and opposite charges. Quarks have 1/3 the electron charge but are never seen alone! In wires electrons do the moving to carry electrical current. In solutions or plasmas there can be positive charge carriers‚ ions or protons. Although the signal to tell electrons to move in wires travels at about 2/3 the speed of light
