what is difference between bolt and screw.?

a Screw usually has threading, a Bolt usually doesn't. Actually, a Screw is shorter than a bolt.

That came from the farmland.Farmers work on their own machinery.When they tear a piece of equipment down they have to keep track of the nuts and bolts so they can put it back together.It was a long trip to town to try to find a new bolt or nut.Thus the phrase Nuts and Bolts.It has become as you know to be used in many different ways.

think pully or wrench. \nwhy do we use pully to lift things, we replace distance for force.\nbut the total work = force *distace is fixed.\nanother example when you use a pipe to make a wrench handel longer fo you can turn the screw. \nIt is technically torque but similar concept.

The only way to get rid of fasteners is to design out the need for them.\n\nI have seen what use to require a screw, washer, 2nd washer and a nut changed to a snap in or a locking tab in place of the fastener.\nWhat is critical is the purpose of the fastener, does someone need to undo the fastener for service, is the expected life of the product such that no service is required.\nAnswering these questions and fasteners can be on the way out.

As I understand it there is no difference. When talking to the general public the word wiggler is often used, but the technical name is undulator.

The UNF is Unified inch screw thread, fine-pitch series.\n\nThe UNJF is Unified inch screw thread, fine-pitch series, with rounded root of radius 0.15011P to 0.18042P.\n\nHope this helps.

Like a rubber block with a metal plate and a bolt going through it.

Fixed Cost means that you pay a certain sum regardless of the actual work performed.\n\nTime and Materials means that you are billed by the actual work (time) and materials spent in getting the work done.

Computer software (or simply software) refers to one or more computer programs held in the storage of a computer for some purpose. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. \n\nHardware is equipment such as fasteners, keys, locks, hinges, wire, chains, plumbing supplies, tools, utensils, cutlery and machine parts, especially when they are made of metal. In the United States, hardware has been traditionally sold in "hardware stores".

Untrue.\n\nHardware is equipment, such as a physical item like a computer monitor, a motherboard, or a hard drive. A key understanding to hardware is that you can't update hardware - you can replace it, but you can't actually update a piece of hardware.\n\nSoftware means a program, written in code. You can't hold software - it's just data. Soft refers to the fact that it's not "set in stone" - you can update code easily.\n\nFirmware is somewhere in the middle. It generally is used to denote a piece of hardware that may be updated - an example is the computer's BIOS chip (stands for Basic Input/Output System) - the chip is hardware, but you can update settings on the chip through a software interface.

How do you mean? \nBroken bones being fastened with screws and plates? Yes.\nA nail from a childhood accident? Yes.\nAliens implanting things? Maybe.\nOr Superhero stuff? Probably not.\nOther ways?

Sydney Harbour Bridge - there are just 16 nuts and bolts... the rest of it is held together with rivets.\nhttp://news.bbc.co.uk/2/hi/uk_news/magazine/4134329.stm

IMA is ideal mechanical advantage. A screw with closely spaced threads has a greater IMA than a screw with threads spaced farter apart. The reason is that for a screw with threads a distance p apart, a full rotation of the screw moves the screw in or out by p. If you are doing the same motion and moving a smaller distance, the IMA is greater. The IMA also depends on the length of the lever arm used to turn the screw. The full equation for IMA for a screw is:\n\nIMA = 2(pi)L/p,\n\nwhere L is the length of the lever arm, and p is the thread pitch.

No difference ,they are all used for dynamic allocation.only syntax difference i guess.

I would say hardware. Hardware is the technical stuff that lets the software work. Like, a cd player: The actual player is the hardware but the software plays on it. You can't play the software without the hardware. With things like computers it's the same way. Anyone can make a plastic or metal machine but if you want it to do something fancy you have to have software to put in it. And if you just have software but nothing to read it or carry out the commands, you'll get nowhere as well. I could own this computer I'm on right now but if they didn't have the software for me to download internet explorer, I wouldn't be here right now. Make sense?

No one seems to know; people argue interchangeably over the two.\n\nThe ref below describes this in more detail.

a dislocation in a metal is basically a defect in the lattice.  there are 2 types of dislocations, edge and screw\n\nan edge dislocation is basically an extra plane inserted half way through the crystal lattice, with the "edge" of that plane being the dislocation\n\na screw dislocation is a shear shift in the lattice and is most easily viewed visually in a textbook
