It depends on how many times the rope 'goes around' the pulleys. If there are 2 ropes 'pulling up' then the mechanical advantage is double. Think about it this way: the tension throughout the rope is constant, so if the object being lifted is 100 pounds, but there are 2 ropes going up from the movable pulley, then each rope has 50 pounds tension on it, but they are the same rope, so you are pulling with 50 pounds force on the rope to create the 50 pounds tension.
Note that the pulley system reduces the amount of force necessary to lift, but the amount of work necessary is the same. Example: if you want to lift the 100 pound weight by 1 foot, you will use 100 foot-pounds of work. With the pulley system as described, you are exerting 50 pounds of force, and must pull the rope 2 feet to lift the weight 1 foot.

∙ 11y agoThe block is movable. The pulley and the block move with load. In this case, the mechanical advantage (M.A) is 2. This is because the load is supported by two parallel ropes and each rope shares the load equally.

How do you calculate the mechanical advantage of a movable pulley?
use calculator
Which is the simple machine that provides the mechanical advantage of 1 the screw second class lever single fixed pulley or single movable pulley?
Single Pulley
Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
What is the mechanical advantage of a stationary pulley?
Its 1 you need more than 1 to improve mechanical advantage i think it's 2 A single pulley means one axel, making the IMA = 1. A double pulley's IMA would = 2, and so on and so forth.
Which is equal to the ideal mechanical advantage of a pulley system?
It only takes half the effort to move an object but twice the distance
What is the mechanical advantage of a movable pully?
for one movable pulley you would get a mechanical advantage of 2
How do you calculate the mechanical advantage of a movable pulley?

What is the mechanical average of a single movable pulley?
I think what you want is the "mechanical advantage". It's 2 .
What kind of pulley has an ideal mechanical advantage of 2?
The kind of pulley has an ideal machanical advantage of 2 is called "Movable Pulley". From, Bryan Hollick
Why is mechanical advantage of single fixed pulley less than single movable pulley?
because lifes hard
How is the mechanical advantage o a movable pulley determined?
I do believe it is equal to the number of ropes you have.
How is a fixed pulley different from a movable pulley?
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
What is the advantage of a moveable pulley?
A single movable pulley gives you a 2:1 mechanical advantage. You can lift move 20 pounds with only 10 pounds of effort.
Anchor the rope at one end and arrange a movable pulley to achieve a mechanical advantage of 2 how much rope you pulled through the pulley?
2m

How does the different type of pulley system affect the mechanical advantage?
Depending on the type of pulley system you have (Fixed/ movable/ combined pulley) using either of these will give you mechanical advantage. The different pulley types are designed to even the weight of the object your pulled out, this will enable you to lift heavier objects with a lighter pull
