A combined pulley system makes it easier to lift an object compared to a single pulley system. By distributing the load across multiple pulleys, the force required to lift the object is reduced.
A common example of a pulley is a flagpole pulley system, where a rope is used to raise and lower a flag. The pulley helps to reduce the amount of force required to lift the flag by distributing the load.
The mechanical advantage of a combined pulley system is equal to the number of supporting ropes or lines attached to the moving pulley or block. For example, a system with two supporting lines would have a mechanical advantage of 2, making it easier to lift a heavy load. The mechanical advantage allows for less force to be exerted to lift a heavy object.
One disadvantage of a combined pulley system is increased complexity, which can make it more difficult to set up and maintain compared to a simple pulley system. Additionally, the multiple pulleys in a combined system can introduce more points of potential failure.
An example of a fixed pulley is a flagpole. The pulley is attached to the top of the pole, and the rope passes through it to help raise and lower the flag. The pulley remains stationary as the flag is moved up and down by pulling on the rope.
make life easy to lift
fixed and movable pulleys can be combined.
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.

yes
No it is not. A belt, for example, goes around a pulley.

An example of a pulley in the bedroom could be a ceiling fan. The mechanism that controls the speed and direction of the fan is typically operated using a pulley system.
