fixed pulley
A fixed pulley is a simple machine consisting of a wheel and a rope. It is connected to some structure which is fixed in position, and doesn’t move. Although its main function is to change the direction of the force applied to this rope, thus making it easier for man to lift heavy objects Technological features include a sturdy frame which stabilizes the whole structure, a smooth rotating wheel that minimizes friction. Fixed pulleys see wide application in construction, shipping industries, and all areas that need lifting.
