How do you calculate the mechanical advantage of a movable pulley?

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 do you calculate the mechanical advantage of a moveable pukkey?
To calculate the mechanical advantage of a movable pulley system, you divide the load force by the effort force. The formula is MA = Load Force / Effort Force. The mechanical advantage of a movable pulley is always 2 because the effort force is half the load force when using a system with a movable pulley.
Which compound machine consists of both fixed and movable pulleys?
A compound machine that consists of both fixed and movable pulleys is called a block and tackle. This system enables a person to lift heavy loads with less effort by utilizing the mechanical advantage provided by the combination of fixed and movable pulleys.
How is the mechanical advantage o a movable pulley determined?
I do believe it is equal to the number of ropes you have.
How are a fixed pulley and a movablepulleydiffrent?
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
What are the three different types of pulleys?
The three types of pulleys are fixed pulleys, movable (or movable) pulleys, and compound pulleys. Fixed pulleys change the direction of the force applied, movable pulleys provide a mechanical advantage by reducing the force needed, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
What is the pulley calculation formula used to determine the mechanical advantage of a pulley system?
The formula to calculate the mechanical advantage of a pulley system is MA 2 number of movable pulleys.
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
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
