The pulley is a simple machine. The purpose of a pulley system is to be able to move a heavy object with less effort. It is made up of a rope or belt that is wrapped around wheels. The wheels are attached to brackets on the sides so that they can turn freely. The brackets are attached to fixed points, such as a ceiling, or in some cases to the object being lifted. The rope is pulled from one end and makes its way through the pulley, while the object is lifted on the other end. The more pulleys that are used, the less effort is needed to lift the object. However, if more pulleys are used, then more rope must be pulled to move the object as far.
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
The driver pulley is the pulley connected to the power source (like a motor), while the driven pulley is connected to the driven load (like a conveyor belt). The driver pulley transfers rotational force to the driven pulley through a belt or chain, allowing the load to be moved or operated.
In a pulley system in equilibrium, the forces acting on the pulley must be balanced. This means that the tension in the rope pulling on each side of the pulley is equal, resulting in a state where the pulley is not moving. This equilibrium condition is reached when the net force acting on the pulley is zero.
To remove a pulley, you typically need to use a pulley puller tool. First, release tension on the belt connected to the pulley. Then, follow the specific instructions for your vehicle or equipment to use the pulley puller to gently remove the pulley without damaging surrounding components.
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.

Things that might cause a pulley to wobble: The pulley is bent. The shaft the pulley is on is bent. The pulley is mounted crooked.
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
No, it is not a pulley. A pulley has to half effort.
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.
If you pry up on the pulley with a bar on each side of it and while keeping pressure on the pulley, hit the end of the shaft that the pulley is on with a brass mallet, the pulley will usually break free.

The crankshaft pulley is the lowest pulley on the engine. Looking at the engine from the front which is looking at it from the passenger side fender the crank pulley is on the bottom of the engine and has a pulley with a pulley behind it with teeth on it.
