Inclined plane- Used for lowering and raising a load. It is also as a ramp.
pulley-
Answer:
There are six types of simple machines — the inclined plane, the wedge, the screw, the lever, the wheel and axle, and the pulley.
1)The lever is a long tool such as a pole or a rod put under an object to lift it. The lever is more efficient when combined with a fulcrum. The fulcrum is another object, perhaps a rock, used to brace under the long tool.
2) The wheel has always been considered a major invention in the history of mankind. But it really would not work as well as it does had it not been for the axle. An axle is a rod or pole centered in the wheel that allows the wheel to turn around it. The wheel then spins in a balanced circle to be used as transportation on a bike or to turn the hands of a clock.
3) The inclined plane is simply a ramp. One end is higher than the opposite end. This allows things to go from a low point to a higher point. Or vice versa. It takes the same amount of work, but less force, to move an object up a ramp than to move it vertically. Gravity makes it easier to move an object down a ramp than up that ramp.
4) Some people might see the wedge as just an inclined plane, although it is actually two inclined planes. However, the use of a wedge is actually different in nature. The wedge is used to separate an object apart. This is needed to cut, tear or break something in two. A wedge can also be used to keep things together or secure things from movement.
5) The pulley is actually a version of a wheel and axle that is combined with a rope, chain or other cord to allow moving something up and down or back and forth. The pulley can be combined with other pulleys to reduce the amount of work necessary to lift huge amounts of weight or to lower them down.
6) The screw is really a twisted inclined plane. It allows movement from a lower position to a higher position but at the same time it moves it in a circle. That makes it take up less horizontal space. A screw can also act to hold things together in some cases.
