end of the building i'm sorry guys another short notice to our a mechanical engineer is bringing in a group of high school students first thing tomorrow they'd like those exhibits for all k or you got to have i'm afraid everyone else is gone so great about the mechanical engineering guys anyway machine inclined plane looks like an outside cellar door to me  opens at nine in the morning and if you're prancing around here when those problems come though years the mechanical engineer and his high school students come on our back on your pedestal like a good that you please i was sort of a mechanical engineer myself you know connectives the principle of evil was my discovery all k anything you say and now i'm afraid you don't appreciate the tremendous significance of these simple devices and a never ending curiosity and the results of all these are all around you and all decide to enrich bank i think about it gus think ahmad use your imagination think thing oh guys i'm a farmer here's what mechanical engineering is done for all of us to work on the farms than for you to machines take the place of muscle now powerful tractors and all kinds of farm machinery take the tough hard work out of farming a lot different from the old days no sir no more long hours walking behind a plow no more laboring by hand to cultivate a crop of backbreaking drudgery from morning to night to day machines do all the hard work wherever you look on the farms across the land you'll see the burden of work taken off the farmer and put on machines wherever there is a job to be done our machines take over doing more work in less time to provide more feed for livestock and a great abundance of food not only for more than one hundred sixty million people in our land today but for millions of people in other countries all over the world in one thousand nine hundred one farm worker could produce only enough for himself and six other people today with the help of machines he can produce enough for sound and seventeen others think of it think of a guy think pretty wonderful when you stop and think about it i guess but the important thing yes it took somebody with creative imagination to see how these simple principles could be applied before those family scenes could become real and whether somebody they can recall engineers you've been married thirty years hav ever stop to think what they meant and think what she could say about them got remember remember remember every appliance you bought me gas had made day so simple now compared to the days when we were first married guys no matter what the job is there are machines that take the hard work out of it and that new home freezer you just bought need one thing to give me extra free time to enjoy myself mark time for us both there enjoy ourselves yeah that's true but it's hard for me to swallow all those like without machines there'd be no power electrical steam or whatever kind that's where the mechanical engineer comes in designing machines which produce power actually there is nothing that a fictional life that mechanical engineering hasn't touched one way or another put your imagination to work again gus let it run away with you and you'll see for yourself for instance in steel plant machines to produce of being you seldom see some little thing everyone is familiar with because of machines your food is better there is more of it and in greater variety mechanical engineers have developed machinery for quick creasing tools in the field and look into the future work is being done in the development of atomic isotopes along safe food preservation everywhere you look there are machines some of them almost human that do many amazing clean you know guys a long time ago she had an idea about flying machines via these machines were practical his ideas were too far ahead of the people in the tire and he worked alone today's progress comes from engineers working together sharing their knowledge and effort in a way unknown and of interest as they were no professional organizations like the american society of mechanical engineers to stimulate such progress and understanding as a result of those are going to vision today that the flying machine every deuce the whole world to a small neighborhood the day almost everyone in america enjoys his own personal transportation system and businesses carry their wares to your own boston to build these paying tools  needed to design and build the machines that make tools again mechanical engineers are needed so when you travel about in your car using all the mechanical advantages  such as power steering think of all of the machine the thousands of operations modern small that have come together to make your grid possible and mechanical this creative work never stops there will always be engineers who can see things and what a man conceives he can do think for a moment what a mechanical engineer might tell you about his job just imagine what he'd say our work is fire eating guy you'll find it everywhere you see it's our job to take raw material adap and useful forms take natural forces highness them to do man's work thankfully speaking we working on the railroad in the new types of power plants for propelling ships across the and other mechanical devices that make it possible to reach the deep caverns of the earth or natural gas  hundreds of other tremendous jobs necessary to carry the natural resources to the places where industry transforms them into useful things people need and enjoy and they have hardly anything that mechanical engineering has not touched in some way or for the things you like to make yourself in every home the result of mechanical engineering of an offsite controls for heating in winter and air conditioning in summer and the equipment itself would not have been amusement and happiness are a result of mechanical engineering pleasure and enjoying carefree moments outdoors all of the entertainment of your choice the news of the world in newspapers or magazine the adventure of land a fiction you are to enjoy because of mechanical engineering we can go on for hours got telling you about the thousands of machines that fell off by engineers to make the things you use every day of your life and magic and matches and magic it's really astonishing gus that all those machines of development and adaptations of these six simple one i once said if i had a place to spend i could move earth but there'd be no point to that what the engineers have done with the ideas the important things that hand drop you use every day is a simple example that if takes you by golly i never thought of that mechanic and engineers work right along with other engineers tools like civil engineers and in mining and metallurgy and chemistry in electricity in just about every field of engineering you'll find a mechanic an engineer these mechanical engineers they do about everything don't they indeed they do you can put it into a precise slot for instance he may be a machine design a working with electrical engineers to make some machine more efficient he may be a specialist in scientific management applying the science of mathematics to quality control on motoring costs or an engineer working on ways to improve the optical systems of your but who has newer ideas on better ways to harvest pack or ship a crop again he may be a designer of a catalytic cracking plant all the designer of oil refineries all the designer of machines used in the petroleum and chemical industries and you'll find the results of his work in the design of machinery for better logging operations and in the design of tools for better woodworking the a professor who spends a lifetime in the classroom but whose hundreds of students will go out year after year adventuring and pioneering to improve your life and everyone that laboratory may be his world and wake and experiment with ways to handle radioactive materials without exposing human beings to the perils of radiation or he may be working on plans for a manmade satellite on machines f steam don't you realize gus the whole history of this land of the oz is reflected in mechanical engineering and that machines are responsible for your country's vast production effort are all of the things that make life worth living if this keeps up it won't be long before our machines will go everything nobody want to have work no guts machines create jobs throughout the thousands from hot work and increased production many coal and the steam boat that called james watt steam engine to work on the ocean the f mechanical engineer will play his spot perhaps now you can understand why the simple machines are so important they are the shining symbols of security and happiness for the future for you and for the benefit of own you know i never realized just how much is meant until now direct result of engineers sharing knowledge with each other and if you can is the sense like the american society of mechanical engineers that the accumulated knowledge and experience of many individuals have been spread through the profession of mechanical engineering to enrich men
