Simple Machines (engineering)

It is a compound machine because it is built with more than one simple machine

1. lever
2. wheel and axle
3. wedge
4. screw

No. A stapler is considered a compound machine since it is made up of more than one simple machines - the lever and the wedge. Some internet sources include the inclined plane and wheel and axle.

wedge and a lever and other stuff

A winch is a geared (lever advantaged) device that is used for drawing large weights. Often comprises a steel cable, hook and spool. Tow truck use a winch to pull a staled auto onto a trailer.

Compound, many different things combine to create a catapult.

lever arm,

torque battery (twisted rope)

winding mechanism

firing control (ratchet system with trigger)

I believe the simple machines in mousetrap would be things such as a lever ( the marble go down a ramp) with a fulcrum, and an input and output force acting on it. ( the marble is weight on the lever)Also, there should be a screw for anything that does a twisting movement, a ramp ( inclined plane), a pulley for capturing a mouse, and a wheel and axel ( anything that function that will spin a wheel.) I'm not to confident on Mousetrap, but those should be the basic functioning machines.

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.

A sewing machine is a compound machine.

To make up a sewing machine, the simple machines you need to use are: an inclined plane, definitely a lever, lots of screws, wheels and axles, a wedge..................... you basically have to use all the simple machines!

A hand pump is not a simple machine. A simple machine is the lever, pulley and screw also might include the wheel and axle, wedge and inclined plane.

A hand pump would have some valves for lifting the water.

There are 6 simple machines known as a wheel and axle, pulley, gear, inclined plane, lever, and a screw. A wheel and axle is anything that rolls. A pulley is like a crane. Pulleys help lift heavy objects easily and safely. Gears help the car stay in control and help it to move. Inclined planes are anything just standing on high surfaces. A lever is like a top of a teeter totter such as seesaw. A screw is like a screw you see everyday. It goes though an object to help hold it in place so it won't fall out or get unstable.

It is an inclined plane.

There are four simple machines used to make the compound machine known as the lawn mower. These simple machines are the wheel and axle, the screw, the lever, and the wedge.

ummm absolutely none its just wood with graphite inside i think you haave got a bit confused....

for me, the spoon is a simple machine. because it is use to eat. a spoon is useful to eat.. only that if it is a compound machines it can use as many.. in compound machines it can be use as many things...

pulley and two other ones that i dont know

Electric Heater ! :)

all simple machines are alike in that they conserve the total amount of work done, but change the amount of force required to do that work by changing the distance over which that force must act.

A machine makes work easier by reducing force and increasing distance.

gears and wheel and axle

Simple machines are considered simple because they usually only have one part or need one force to work.

Self powered machines were first used at the start of the industrial revolution. Tabulating machines were known to the ancient Greeks, such as the famous Ankylothera Device. The Romans, too, had contraptions that moved and worked much as we might imagine modern machinery might, though not driven by piston engines. Some of these, such as the catapult, were known as engines of war. The water wheel is considered a fairly crude machine, and can was used to grind grain or wash clothes.

Archimedes invented a "screw" for irrigating crops, another clever early machine. The clepsydra, a water clock, could also be considered a machine.

1. Pulley-a simple machine that uses grooved wheels and a rope to raise, lower, or move a load.
2. Lever- a stiff bar that rests on a support called a fulcrum which lifts or moves loads.

The six simple machines are wedge, inclined plane, screw, the wheel and axle,lever and the pulley are the six simple machines.

The inclined plane (you'll see why I started with this first) is simply a ramp or slope that reduces the amount of effort force needed to move the load.

The wedge is two inclined planes put together back-to-back.

A screw is an inclined plane wrapped around a rod.

The wheel and axle is a circle attached to a rod.

A lever is a simple machine consisting of a rigid bar pivoted on a fixed point, called the fulcrum, and used to transfer the effort force in order to raise the load. There are three levers: Class 1,2,and 3.

Last but not least, the pulley is a grooved wheel with a rope or chain running through it. There are two types of pulleys: fixed and moveable. There are two systems, both consisting of pulleys: the block and tackle and compound pulley.

Hope this helped!
