Not necessarily. Some fans use belts on pulleys to transfer the rotary motion of the motor to the fan blade, while others use gears, and some are direct drive.
yes the do have pulleys
Many people use pulleys in their jobs. The rides like Supreme scream, which go vertically up and down have pulleys in them. Elevators have pulleys in them, and people who ship cargo use pulleys in their cranes.
Archimedes (not a group, a guy) invented pulleys as well as other simple machines.
assuming that your question is what jobs are pulleys used for... then the answer is any job that you need to lift something that is heavy. The pulley give a mechanical advantage when used together with other pulleys to apply more force to move the object
The Giza Pyramids were constructed using step-walking wooden four-lobe pinion-pulleys with a mechanical advantage of 2.8 (MA=2.8) This ancient pulley was unknown to the modern world until 27 August 2006. The design and operation of this pulley is nothing like any pulley known in the modern world. Google four lobe pinion pulley.
There are three main types of pulleys: fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are attached to a stationary object, movable pulleys move with the load, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
My '95 galant s 2.4 has an electric fan with 2 fans. Not sure if you need to change the pulleys on them.
Examples of pulleys include elevator systems, flagpoles, and weightlifting machines. These devices use pulleys to change the direction of a force or to provide mechanical advantage in lifting heavy objects.

The three types of pulleys are fixed pulleys, movable (or movable) pulleys, and compound pulleys. Fixed pulleys change the direction of the force applied, movable pulleys provide a mechanical advantage by reducing the force needed, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
There are three main types of pulleys: fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are attached to a structure and change the direction of the force applied. Movable pulleys are attached to the object being moved and provide mechanical advantage. Compound pulleys combine fixed and movable pulleys to increase both the weight capacity and mechanical advantage.
Pulleys are simple machines.
The three kinds of pulleys are fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are anchored in place and change the direction of the force applied. Movable pulleys have a pulley that moves with the load, reducing the force needed to lift the object. Compound pulleys consist of multiple pulleys working together to provide mechanical advantage in lifting heavy loads.
Some examples of pulleys include clothesline pulleys, flagpole pulleys, and elevator pulleys. Pulleys are simple machines that consist of a wheel with a groove around its circumference and a rope or belt that moves around the groove to lift or lower objects.
Yes, the belt system has pulleys.
Gears Are Relevant To Pulleys Because Gears Turn Into Circles So Do Pulleys The Difference Between A Gear And A Pulley Is... A Pulley : Pulley Has Strings To Hold On One Goes Up And The Other One Across A Gear : A Gear Has No Strings To Hold On Woozworld/Weeworld Try These Games There AWESOME!
