Simple machines are the most basic ways of making work easier or more efficient. There are 6 of them (if the different kinds of levers are considered the same simple machine): Inclined plane: Spreads out the work needed to move the object, so less is needed at once. Lever (first class): Changes direction of force applied. Load is on the opposite side of the fulcrum than the side that the force is applied on. Lever (second class): The load and force are on the same side of the fulcrum, with the force being applied further from the fulcrum. The work is easier, but the load isn't lifted as high. Lever (third class): Similar to second class levers, the load and force are on the same side as the fulcrum, but the force is closer to the fulcrum. The work is therefore harder, but the load is lifted more efficiently Wheel and axle: Just what it sounds like. The wheel is a simple, but brilliant tool that makes it so the inside and the outside make the same amount of rotations in the same amount of time, but move at different speeds. Turning the axle makes the outside of the wheel move fast, while turning the outside of the wheel makes turning the axle easy. Pulley: Made up of a wheel and a rope, the rope fitting on the groove of the wheel. This machine can either change the direction of the force, increase the efficiency of lifting a load, or make lifting the load easier. The more times the rope goes around a set of two wheels, the more efficient the pulley gets Screw: Changes the direction of force from around in a circle to down. The tool the "Screw" was named after this simple machine. Wedge: Also changes the direction of force from in one direction to out. This is used by scissors, axes, knives, or anything else that can cut.
the formulas for simple machines help find the ama, ima, and the efficency
Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.
Machines are made or designed to help men do jobs easier. even before they used simple machines to help them do heavy work such as pulleys and lever.
Simple machines increase mechanical advantage.
a compound machine is a combination of simple machines
Oh yeah. Simple machines really help me make better use of my your. Ofcourse it help us a lot.
Help us in our everyday lives:)
Simple machine helps us to increase the power and force for change.
its make our life easier
Simple machine help us do work like lifting heavy things that we cant lift. This was done by an 8th grader at berea middle school.
the 6 simple machines are used to help us in our daily which means it give us less time to do it ourselves . when the tools are doing all of the work. the 6 simple machines are listed here: inclined plane, pulley, wheel and axle, lever, wedge, screw and those are the 6 simple machines.
the formulas for simple machines help find the ama, ima, and the efficency
Yes,because it help us just like a simple machines.
its make our life easier
· Oil them regularly · Keep them on their box · Keep them out of reach of children
They make work easier
Humans created machines to help them selves. But machines enslaved humans.
