A pulley is a simple machine that can be either fixed or movable. A fixed pulley is anchored in place and changes the direction of the force applied, while a movable pulley moves with the load and reduces the amount of force needed to lift it. Both types are used to lift heavy objects more easily.
A compound machine that consists of both fixed and movable pulleys is known as a block and tackle. This system combines multiple pulleys to reduce the amount of force needed to lift heavy loads. The fixed pulleys change the direction of the force applied, while the movable pulleys help distribute the weight, making lifting easier and more efficient.
Single fixed pulley
A crane is a movable pulley
That's called a lever.
To achieve a mechanical advantage of 3 using pulleys, you can use a combination of fixed and movable pulleys. One common arrangement is to have one fixed pulley and one movable pulley. In this setup, the load is attached to the movable pulley, which is supported by a fixed pulley above it. The user would pull down on the rope, effectively distributing the weight of the load over three segments of rope, resulting in a mechanical advantage of 3.
Single Pulley
A compound machine that consists of both fixed and movable pulleys is called a block and tackle. This system enables a person to lift heavy loads with less effort by utilizing the mechanical advantage provided by the combination of fixed and movable pulleys.
A ladder is not a simple machine at all; it is just a set of movable steps that allows the real machine - you! - to move with better handholds and footholds.

The fixed turning point of a simple machine is called the fulcrum. The fulcrum is the point around which the machine rotates or pivots to perform work.

You can't have a "fixed" "movable" bridge, the two terms are contradictory.

Pulley belongs to one of the class of Simple machines They are two types of pulleys 1. Fixed pulleys 2. Movable pulleys. Examples Fixed pulley : flag poles, sail boats, simple cranes, curtains in theatres, conveyor belt, simple line elevators Examples Movable pulley : Cranes , amusement park rides , elevators and cable cars using movable pulleys.
A fixed pulley is a type of simple machine known as a pulley. It changes the direction of the force applied to lift an object but does not provide any mechanical advantage.
Yes an elevator is a movable pulley!
