How do you calculate the mechanical advantage of a movable pulley?
use calculator
How do you find the mechanical advantage of a simple machine?
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
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
How do you make a pulley project for a third grade child?
Ooo,...this sound like it would be fun! Well probably one of the most interesting things about pullys is that if the pully is on the movable part of the line it provides you with a mechanical advantage of 50%! That is to say, properly set up you can lift a 10 pound weight with just 5 pounds of force. If the pully isn't moveable it only provides a fixed point from which to change the direction of pull and no mechanical advantage at all! In this it take 10 lbs of force to move a 10 lb weight. This should be pretty easy to show a 3rd grader and fun too!
What mechanical advantage of movable pulley?
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.
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?
use calculator
What is the mechanical average of a single movable pulley?
I think what you want is the "mechanical advantage". It's 2 .
How is the mechanical advantage o a movable pulley determined?
I do believe it is equal to the number of ropes you have.
How do you find the mechanical advantage of a simple machine?
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
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
What is the mechanical advantage of single fixed single movable pulley system?
The mechanical advantage would be 1 because the force required to life the mass of an object becomes 1/2 the original weight of the object.
Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?

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 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.
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.
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
