Answer:
1.Pulley-lifting or raising and lowering a load easier.
2.Wheel and axle-raising weights and carrying or transport loads over land and travel a long distance.
3.Wedge-cutting or splitting certain materials apart.
4.Lever-lifting, removing, or pulling out objects easily
5.Inclined plane-lift or raise a heavy object by moving up a slope.
6.Screw-fastens or hold fastened things and used to hold lifted objects.
Explanation:
:)
1.A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt.
2.The wheel and axle is a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
3.a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.
4.a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
5.An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.
6.A screw is a mechanism that converts rotational motion to linear motion, and a torque to a linear force. It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside.
