no its a grooved wheel with a rope running along the groove
the above answer is wrong because it is the definition of a pulley.
Yes that is true. A wheel and axle is a simple machine consisting of two wheels of different sizes that rotate together.
It sounds like you are describing a gear system with two gears of different sizes that interlock and rotate together. Gears are commonly used in machines to transmit power and change speed and direction of rotational motion.
the wheel and axle is a simple machine made from two circular objects and are different sizes that are attached and rotate together and it is a lever that can rotate to 360 degrees
Different things in a machine can rotate. In a motor, the rotor will rotate or revolve. We also find shafts, gears, pulleys, cams, flywheels and a number of other parts that spin.
wheel and axel
Two circular objects of different sizes that rotate together is a wheel and axle. Inclined plane wrapped around a central cylinder or bar to form a spiral is a screw.

No.
A gear is a toothed wheel that meshes with another gear to transfer motion and power in a machine. It looks like a circular disc with teeth around the edge. When two gears mesh together, the teeth interlock and rotate, transferring force and changing the speed or direction of motion in the machine.
several gears that rotate together.
several gears that rotate together.
True. A lever is a simple machine consisting of a rigid bar that can pivot, or rotate, around a fixed point called the fulcrum. The lever is used to transmit a force from one point to another by applying effort at one end.
