Set or Course 1 pulleys have a mounted shaft. That is, the shaft is “fastened” or anchored in place. A mounted pulley is a drive used to change the course of the rope (called a belt simply because it helps make 1 flip). Fastened pulleys have mechanical positive aspects of mounted pulleys. Energetic pulleys or 2-phase pulleys have free shafts. That is, the axis can go “freely” in place. Relocating pulleys are used to change forces. Energetic pulleys have the mechanical gain of two pulleys. That is, if a single finish of the rope is stationary, pulling the other stop of the rope will exert 2 times the force on the item connected to the pulley. A composite pulley block is a mix of a fixed pulley block and a movable pulley block. Blocks – Blocks are composite pulleys in which several pulleys are mounted on every axle, additional incorporating to the mechanical advantage. Pulleys can alter the direction of the drive.
