By simple machines, I assume you mean machines powered by muscle but using leverage such as levers, screws, block and tackle devices. Is that what you mean? If so, these devices increase something called "mechanical advantage".
Start with levers. The usefulness of a lever depends on where the fulcrum is placed. If the fulcrum is in the centre of a lever such as with a see-saw, there is no mechanical advantage at either end. That's why kids of similar weights can suspend the kid on the other end of the see-saw up in the air just to be rascals. Now if the fulcrum is closer to one end than to the other, the person farther from the fulcrum can exert more force than the person closer to the fulcrum. Think of a crow bar. One inserts an inch or two of the bar at the point where one wants to apply force. Pushing on the other end of the bar (perhaps two, three, four feet away) exerts a lot of force at the other end. The same effect allows you to lift a car with a jack. You push down a foot on the jack handle and the jack platform rises perhaps half an inch.
Simple machines either reduce the amount of force required be increasing the distance traveled or reduce the distance traveled be increasing the force required. Depending on the application both of these my make work easier.
A simple machine makes the job "easier" because it reduces the necessary force.
But you pay for it by exerting the smaller force through a greater distance. So the
product of (force) times (distance) doesn't change, and that product is exactly
the scientific definition of "work".
Yes. By definition a simple machine reduces the direction and or magnitude of a force. Since Work = Force • Distance, when the simple machine reduces Force, it also reduces Work.
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force
Each of these simple machines work around a pivot point except the
When simple machines work together, that forms a compound machine.
ANSWER: work input equals work output
There are many different types of machines in the world. Machines help people do work, and make it easier for them. There are six simple machines, and the rest are classified as complex. These six simple machines are: 1) Pulley 2) Screw 3) Lever 4) Inclined Plane 5) Wheel and axle 6)Wedge
Simply put, a simple machine makes the work much easier. Simple machines reduce the amount of force needed to do the work. A pulley, for instance, is a great example of a simple machine.
They do not. Simple machines reduce the effort used to do a task.
No you still do the same amount of work
Yes. Use simple and compound machines always get things done faster and better.
No you still do the same amount of work
They increase the amount of work over a longer period of time.
Because the action requires the same amount of force.
A machine decreases the amount of force needed to work, as it distributes the force throughout a larger distance.
Because less force is required to accomplish the same amount of work.
Simple machines will reduce the input force, but can allow you to travel farther distances. Your'e body is not putting in as much force, your body will allow you to do more work for a longer time....but yes,it decreases the input force.
it is called as simlple machines because it easy, simple,good handling, so it will do the work easier and complete the work easier...
simple machines are put together by connecting. for example, in cars. simple machines work together by putting their strength
