Q:Our teacher has specifically asked us to search for the ACM definition of computer science, as well as its elements. I've been looking all over, but to no avail. Anyone mind helping me out?

Computer Science Definition

Q:industrial era

Because automation reduced the need for workers.

Q:Farm machinery operates under very difficult situation in the field. For example, paddy fields are muddy with pesticide, fertilizer and other chemicals in which tractors containing steel and aluminum components operate. This results in corrosion of metallic component. Propose methodology for preventing corrosion in farm machinery.

i may desire to be a sort of, as there is at present plenty sh**e in my existence lets paintings proper collectively. purely call me Compo. 635 Litre Double Chamber ComposTumbler ?455.00 boost your composting output with the newest addition to the common-to-use Compost Tumbler relatives; the unique layout of the 635 Litre Double Chamber ComposTumbler divides the drum into 2 sections for an impressive speedier flip-around time. The tumbler efficiently operates as 2 separate drums to provide you higher flexibility on your composting and push 334 litre batches with the aid of extra quickly.

Q:I work at a pizza place, and while washing dishes, a cheese grater fell off the shelf and broke. A piece that is important to the cheese grater's functioning. Now, mind you, it fell off the shelf and I was not touching it. My manager wants me to either pay cash, or he will just deduct it from my check, when I argued with him that it is a cost of doing business.Is this legal, and what sound I do?

i dont think they are allowed to do that.

Q:i have a combine, tractor, and sprayer. what else? i bought the sprayer off my brother but i don't know what types of fertilizers and sprayers i need for a apple orchard and wheat farm..

a $100,000 combine a 25000 dollar tractor, a gang plow or disc a grain drill 13-13-13 fertilizer don't know what chemicals you need for the orchard.

Q:Just thread pipes?Is that all they do because thats what I keep hearing

I would say no, because almost every job has more then just one purpose then like u said threading pipes

Q:Will operating heavy machinery adversely affect my ability to drink alcohol?

Work is the curse of the drinking class. --George Bernard Shaw

Q:I'm talking about both commercial farms and subsistence farms. When I say mechanization, I'm referring to tractors, harvesters, threshers etc

I find tractors a big help to carry heavy loads plough the fields cut the hay and carry big bales of hay/straw..so thats an advantage farm machinery make farming a bit easier and you are able to do work quicker (i.e harvesting) and with out the need of to many labourers and less physical strain... disadvantage: they can be dangerous if not used/handled properly they can be expensive to buy compare to employing workers need fuel and maintenence which can be expensive they are not environmentally friendly

Q:what is the main functions of hydraulics in a machinery?

I agree that it is to move parts and to transmit motive power. However, I submit that one of its primary advantages is that it can multiply force by using the effects of fluid dynamics. This is why you see hydraulics used in applications where very high loads are required (aircraft control surface actuation, bulldozers, moving huge counterweights, etc).

Q:What's the difference between an automatic watch and a mechanical watch?

The power source automatic mechanical watch is a shaking table, worn on the hand, people on the move is inevitably affected by vibration, the table has a collection, conversion to mechanical vibration rotational energy of the table, worn on the hand if it hasn't been tightened spring by the shock will be automatically wound, if you leave the table put in place without vibration generally within 24 hours it stopped. The disadvantage of this kind of automatic mechanical watch is that it is much thicker and thicker than the ordinary mechanical watch. The advantage is that it does not need to be artificially wound up. It is rare now.
