A single pulley can change the direction of a pulling line. The direction change may help in pulling the line over a corner or around an obstacle. Or the direction change may allow better use of the available pulling force. Also, the single pulley can relocate the pulling point.
For example, suppose we wish to lift a weight some distance into the air. If I am the pulling force, then my first problem is that I cannot lift the weight any higher than I can reach. But if the pulling line is looped over a pulley some distance above my head, relocating the pulling point, I can potentially lift the weight just about up to the pulley's height. And now the pulley has given me another advantage. I can leverage my own weight, pulling down on the line, to lift the weight upward.

Is a single fixed pulley superior than a single movable pulley?
A single movable pulley is typically considered superior to a single fixed pulley because it reduces the amount of force needed to lift an object. The movable pulley changes the direction of the force applied, making it easier to lift heavy objects.
What is a single pulley system?
A single pulley system consists of one pulley that is attached to a fixed point. It is used to change the direction of a force, making it easier to lift or move objects. By reducing the amount of force required, a single pulley system can increase efficiency in lifting operations.
What is velocity ratio of single fixed pulley?
The velocity ratio of a single fixed pulley is 1. This means that the input and output speeds are equal. The pulley simply changes the direction of the force applied.
What is the mechanical advantage of a single fixed pulley?
Thew pulley changes the direction of the effort force.
How is a window blind an example of a pulley?
Oh, dude, it's like this - a window blind uses a pulley system to raise and lower the blinds. The cord you pull is attached to a pulley at the top, which helps you easily adjust the height of the blinds. So yeah, next time you're adjusting your blinds, just remember you're basically a master of pulley physics.
Uses of single pulley?
it can help by pulling heavy loads using a rope
What are 2 different kinds of pulleys?

What kind of pulley is a fishing pole?
Single movable pulley
The simple machine that provides a mechanical advantage of one?
Single fixed pulley
What is a single moveable pulley?
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
Why is mechanical advantage of single fixed pulley less than single movable pulley?
because lifes hard
