Simple MachinesDefinitionsMachine- A spin that makes give way easier by changing the speed , direction, oramount of a force.Simple Machine- A device that performs engage with only one movement. Simple utensils include lever, wheel and axle, lean(p) plane, screw, and wedge.Ideal Mechanical value (IMA)- A weapon in which work in equals work outsuch a machine would be frictionless and a 100% cost-effective IMA= De/DrActual Mechanical Advantage (AMA)- It is pretty much the opposite of IMA meaningit is not 100% efficient and it has friction. AMA= Fr/FeEfficiency- The amount of work put into a machine compared to how much consumptionfulwork is put out by the machine always between 0% and 100%.Friction- The force that resist motion between two surfaces that are touchingeach other.What do we use machines for?Machines are utilize for many things. Machines are used in customary lifejust to make things easier. You use many machines in a day that you might takefor granted. For exam ple a simple so-so(predicate) broom is a machine. It is a form ofa lever. Our country or world would never be this evolved if it wasnt formachine. Almost every thing we do has a machine involved. We use machines tomanufacture goods, for transportation, ect.In the W=F*d equation the trade of between force and distance is as youuse a machine the force goes down and distance goes up. If on that point was no frictionthey would be equal and trade.There are sestet simple machines. They are a lever, pulleys, inclined plain,wheel and axle, screw, and wedge. The lever is used very often an example of alever is a broom. Your contri bute hold of is the fulcrum and when you sweep it is a lever. Alever consist of a fulcrum, effort, and resistance. A pulley is used to lift orpull objects with a gain. To get a advantage it matters how many lines aregoing to the load. For example if in that location is 3 lines to the load it is a 3/1advantage. A inclined plain is used to lift an object easie r but with more work. preferably of lifting it straight up you push it a greater distance but with lessforce. A screw is a inclined plain masked well-nigh a cylinder post. Its like aramp around the screw.A wedge is a inclined plain with one or two sloping sides. Chisels,knives, and ax blades are examples of wedges.IMA is ideal mechanical advantage meaning a frictionless world with 100%efficiency. It is saying that work in and work out are exactly the same.
