Aug 04, · A fixed pulley consists of a wheel fixed to a shaft and is used in conjunction with a belt to transfer energy to another fixed pulley. A movable pulley consists of a shell, a movable wheel and a rope. Movable pulleys are also know as block and tackle. Experts choose flagpoles as applications of fixed pulleys, while movable pulleys are utilized in modern elevators and weight lifting machines. What makes a movable pulley unique is that only one part of the rope is attached to a fixed object, like a bar or a beam. When both parts of the rope are attached to a fixed object, this is known.

Although, experts say that movable pulleys require more rope pulls by the user as the weight has become lighter, but fixed pulleys require less pulls. According to TeachEngineering, fixed pulleys enable the user to w advantage of what happens if you get aids, balance an object and help raise objects above one's head. Movable pulleys are useful to raising objects below one's head.
These pulleys are easiest to lift objects, as the mechanical advantage increases in tandem with the inclusion of more ropes, as cited by TeachEngineering. Pulleys are one form of simple machines in addition to screws and levers.

A compound machine that consists of both fixed and movable pulleys is a fixed pulley. This machine changes the direction of the force on a rope or belt that moves along its circumference. As the name suggests that this pulley is stationary and is fixed to support like wall or ceiling and the rope/chain passes through it. These are vital mechanical devices as they change the direction of the object, which is very helpful. Movable pulleys are different types of pulleys as they move with the object and unlike the fixed pulley; they need little effort to lift the heavy objects. They multiply the effort made .
A pulley is one of the six simple machines that human beings use to help them lift and move objects. All pulleys consist of a basic level of a wheel with a rope strung around it. Depending on the pulley arrangement, a pulley may either provide a mechanical advantage that allows a heavy load to be lifted with less work, or it simply allows the same amount of force to be applied in a different direction.
Other pulley systems may allow both of these benefits. Though they can rotate or lift the weight up and down, they cannot move freely in any direction. One single moving pulley is sustained at the two ends of the same chain but has the advantage of two.
While in fixed pulleys the direction of the force can be changed, the same does not happen in the case of moveable pulleys. Usages of movable pulleys include:.
This combines the benefits of both a fixed and a moveable pulley. In a compound pulley, the weight is attached to the wheel of a moveable pulley, which itself is strung to a rope attached to a fixed pulley. With a compound pulley, you can redirect the required direction of the force as well as the total workload for the force. A block-and-tackle pulley system consists of several fixed and moveable pulleys arranged parallel with one another; fixed pulleys aligned with fixed and moveable pulleys with moveable.
Each compound pair is attached to the next pair, and each set reduces the total work required. This pulley system is popularly attributed to Archimedes, the famous ancient inventor and mathematician. Cone pulley: As the name denotes, these types of pulleys consist of cone-shaped pulleys arranged together for moving the weight. The arrangement is such that the pointed end of one the cone-shaped pulley is attached or pointed towards the larger base of the other.
These consist of more than two pulleys, depending on the weight and the speed required for movement. These are mostly used in construction sites and as part of other machines. Some users of cone-shaped pulleys:.
