Why do engineers put power lines so that they are slack in hot weather?
in the winter season materials such as rubber insulators and copper wire shrink and in the summer they expand just like wood. Therefore slack is needed on powerlines in relation to the weather so there is a little give to them. Engineers have nothing to do with the slack in the lines, it occurs naturally. In the sunlight objects expand a little due to the heat. This goes for roads, bridges, sidewalks, shingled roofs and hanging power lines. They sag more in the summer than in the winter. Engineers actually have to find ways so that they wont get slack. This expansion and contraction of any given material will actually shorten the life of it over time, and it will have to be replaced more often.
What method do engineers use to communicate an objects dimmensional information?
Answera 3d drawing with dimensions...or a series of 2d drawings with dimensions, sections, and plan views.Usually the type of 3d drawing is an isometric - coming from Greek Isos ("equal") and metric ("measure"). In an isometric drawing, the object's horizontal lines are drawn 30 degrees to the horizontal, and all co-planar, co-directional lines are drawn parallel (as opposed to perspective drawings in which an object appears to get smaller the farther away from you it gets). The dimensions are just enough to adequately recreate the object, none missing to leave room for guessing.Dimensions are made up of extension lines and dimension lines. The extension lines extend from the object, usually starting 1/16" or so from the edge of the object itself. The dimension lines have any of a number of types of arrowheads and are drawn between the extension lines, usually with the dimension centered within the dimension line.
What is the distance between railway lines?
The distance between railway lines varies depending on the type of railway track and the country. 60 percent of railway lines in the world, however, use the 1,435 mm standard gauge.
Why are railway tracks put down in summer?
Because during summer the weather is warmer and the metal rail lines will have expanded to their maximum length. If they were fixed rigidly in place during cold winter weather when they were later subjected to the heat of summer they would expand and buckle.
What does 380 volts between phases mean?
You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.
Why is it advisable to allow telephone lines to sag when stringing them between poles during the summer?
Because they will contract in the winter. If you strung them tightly during summer, when the cold weather arrived, the lines would shrink, and maybe snap.

How many lines of code did engineers and technology professionals put into the iGen4 Digital Offset printers?
8 million lines
Why electric transmission lines between two poles are found to sag in summer?
The metal conductor in the line contracts in the cold of winter making the line more taunt, and expands making the line longer in the summer's heat. Thus the summer 'sag.'
What are some examples of what an engineer does?
Different engineers do different things. Civil engineers may design dams, bridges, roads. Mechanical engineers design factories, production lines. Electrical engineers may design power systems, and chemical engineers design chemical manufacturing processes. Safety engineers design safe working procedures, and operating engineers operate boilers, locomotives, cranes, and large equipment. Aeronautical engineers design airplanes and spacecraft, and Marine engineers design ships. And there are others as well.
Write a summer vacation for my exam only five lines ia'fte write?
i will write about summer vacation .my summer vacation it is nice
Why do power lines sag lower between telephone poles in summer than winter?
the metal inside the wire heats up leading to the expansion of the wire.
What is a business available on many commercial air lines and rail lines?
There are many businesses available on many commercial air lines and rail lines. For example, there are businesses available for railroad fixing, train fixing, and plane fixing for engineers.
What has the author Gayle F Miner written?

What kind of machinery do sound engineers normally deal with?
Sound Engineers (also known as Audio Engineers) work with equipment and machinery that specializes in recording and manipulating sound. Often, they work with amplifiers, monitors, speakers, mixing boards, microphones and audio lines.

How do you change a fuel filter on a 1996 Chevy S10 pickup and where is it located on the truck and a diagram please?
unscrew the lines going into and out of it pull it out and reinsert the new one then tighten the lines
