Answer:
LEVER — Levers are varied, but all have a few components. They all have an arm, a straight, relatively inflexible part, like the handle of an axe or the entire length of a see-saw, that needs to be unbreakable and relatively unbendable. They also have a fulcrum, or pivot point on which the lever rests and pivots.
INCLINED PLANE — a flat supporting surface tilted at an angle, with one end higher than the othe
PULLEY — A pulley which has sealed ball bearings, is very strong, has a moderate weight, is not too big, has a large sheave, has a large anchor and becket hole will typically be more expensive than a pulley that does not have these characteristics.
WEDGE — simple machine that consists of two inclined planes, giving it a thin end and thick end.
SCREW — screws are overall size, the shape of the head, slot type, length, material, and thread type.
WHEEL AND AXLE — The wheel and axle consists of a round disk, known as a wheel, with a rod through the centre of it, known as the axle. This system uses angular momentum and torque to do work on objects, typically against the force of gravity. The wheel and axle simple machine is closely related to gears.
