Load "L" is attached to the movable pulley. A rope is fixed at a point in ceiling that passes through the movable pulley.
In order to lift the load "L" by "X" meters, the effort "E" needs to travel the distance of 2X meters. (The entire rope needs to be pulled by "E" for a distance of 2X.)
Now, Velocity Ratio equals (Distance traveled by "E") divided by (Distance traveled by "L")
So it becomes : 2X/X. This equals to 2
Since it is a ratio. it has no units of measurement.

A single movable pulley has a velocity ratio of 2 because it changes the direction of the force applied on the load while sharing the weight of the load between the two strands of the rope. This results in the effort being halved compared to the load, giving a velocity ratio of 2.

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 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.
Why the value of single movable pulley is 2?
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
How does a movable pulley look like?
A movable pulley consists of a single pulley that moves up and down along a rope or cable. It is typically attached to the object being lifted, while the other end of the rope is anchored in place. When force is applied to pull on the loose end of the rope, the object attached to the pulley is lifted.
How is the design of a fixed pulley different from the design of a movable pulley?
A fixed pulley is stationary and changes the direction of force, while a movable pulley moves with the load and provides a mechanical advantage by distributing the force over multiple ropes. Fixed pulleys have a single attachment point, while movable pulleys have two attachment points—one fixed and one moving.
What are 2 different kinds of pulleys?
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
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 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.

A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
What are the types of pulley?
movable single multiple fixed inclined
What is the mechanical average of a single movable pulley?
I think what you want is the "mechanical advantage". It's 2 .
What is the difference between single fixed pulley and a fixed pulley?
Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
