A wheel with a broad rim, or grooved rim, for transmitting power from, or imparting power to, the different parts of machinery, or for changing the direction of motion, by means of a belt, cord, rope, or chain., To raise or lift by means of a pulley.
It means, facing away from the pulley
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
To convert 1400 RPM to 2800 RPM using a pulley system, you would need to use a pulley ratio that doubles the speed. This can be achieved by using a smaller drive pulley on the motor (connected to the 1400 RPM source) and a larger driven pulley on the output shaft. The size ratio of the drive pulley to the driven pulley should be 1:2, meaning for every rotation of the drive pulley, the driven pulley makes two rotations, effectively doubling the RPM to 2800.
A fixed pulley does not provide any mechanical advantage, meaning it does not reduce the amount of force needed to move an object. Additionally, it changes only the direction of the force applied, not the magnitude.
A disadvantage of a fixed pulley is that it does not provide any mechanical advantage, meaning it does not change the direction or magnitude of the force applied. This can make it challenging to lift heavy loads without additional force.
To make a single fixed pulley work, you need to apply an input force to one end of the rope. The pulley redirects the force in the opposite direction, allowing you to lift or move an object with less effort. The mechanical advantage of a single fixed pulley is 1, meaning the output force equals the input force.
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
a coumpound pulley is when there is a fixe pulley and movable pulley working together

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.
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
