The first electronic computers went into operation in 1945 There are hairs on your jacket There are books on . There have been a number of high-rise buildings in this city The teacher is explaining the construction method with the students standing beside him At one time it was thought that the earth is the center of the universe It is well known that. It is generally accepted that the experiences of the child in his first years largely determine his character and later personality The largest foundation sinks the most and the smallest the least Feeling that the police would recognize him, he never went out in the daytime I did not feel terribly shocked, having expected all this Weather permitting, we will go on a tour of the lake district next week Taken in time, the measures will be quite effective It is altogether a mistake to regard science as dry and difficult – much of it as easy as it is interesting As I snooze she talks of anything, everything, all the things that women talk of: books, music, dress, men and other women

1.The automation of a new product or plant requires a very large initialinvestment in comparison with the unit cost of the product, although thecost of automationmaybe spreadamongmanyproductsand overtimeAutomationmayimproveineconomyofenterprises,societyormostofhumanity. For example, when an enterprise invests in automation,technology can help recover its investment, or a state or countryincreases its incomeduetoautomation.2.Most refrigerators, air conditioners, pumps and industrial machineryuse AC power whereasmost computers and digital equipment use DCpower. AC power has the advantage of being easy to transform betweenvoltages and is able to be generated and utilized by brushless machinery.DC power remains the only practical choice in digital systems and can bemoreeconomicaltotransmitoverlongdistancesat veryhighvoltages.3.Other CAE programs commonly used by mechanical engineers include productlifecycle management(PLM)tools and analysistools used to perform complexsimulations.

1.The automation of a new product or plant requires a very large initial investment in comparison with the unit cost of the product, although the cost of automation may be spread among many products and over time. Automation may improve in economy of enterprises, society or most of humanity. For example, when an enterprise invests in automation, technology can help recover its investment, or a state or country increases its income due to automation. 2.Most refrigerators, air conditioners, pumps and industrial machinery use AC power whereas most computers and digital equipment use DC power. AC power has the advantage of being easy to transform between voltages and is able to be generated and utilized by brushless machinery. DC power remains the only practical choice in digital systems and can be more economical to transmit over long distances at very high voltages. 3.Other CAE programs commonly used by mechanical engineers include product lifecycle management(PLM)tools and analysis tools used to perform complex simulations. Analysis tools may be used to predict product response to expected loads, including fatigue life and manufacturability.
