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.
What are the three kinds of pulley?
1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load
What is the mechanical advantage of a simple pulley?
If the pulley is fixed to the ceiling and the rope passes over it, then the ideal MA is 1, but there's some friction loss in it. If one end of the rope is fixed to the ceiling and the load hangs from the pulley, then the ideal MA is 2.
How does increasing the number of pulleys affect the ideal mechanical advantage and efficiency of pulley system?
Ideal mechanical advantage is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load.The MA of a pulley is equal to the number of supporting ropes.If the load is supported by one rope , the M.A of the system is 1. Efficiency is 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by two ropes , the M.A of the system is 2. But Efficiency is still 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by three ropes , the M.A of the system is 3. Efficiency is still 1 for ideal pulley ( No loss of energy due to friction) .And so on.Read more: How_does_increasing_the_load_affect_the_ideal_mechanical_advantages_and_efficiency_of_a_pulley_system
Does a simple pulley change the direction of force?
A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.For a class 1 pulley, the pulley is stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.

What are two types of pulleys?
There are two basic types of pulleys. When the grooved wheel is attached to a surface it forms a fixed pulley. The main benefit of a fixed pulley is that it changes the direction of the required force. Another type of pulley, called a movable pulley, consists of a rope attached to some surface. The wheel directly supports the load, and the effort comes from the same direction as the rope attachment.
What is the IMA of a single fixed pulley?
Nothing, really. A slight loss due to friction. If the pulley is fixed to the load, then there is a 2:1 advantage.
What is the ideal mechanical advantage of a fixed pulley raising a 1 kg can of paint a distance of 10 m?
The mechanical advantage doesn't depend on the distance the load moves, any more than it depends on the color of the paint in the can. If the pulley is hanging from the ceiling and you pull down, then the ideal MA is 1 . If the rope is fixed to the ceiling, the pulley rides on it, and the load is hanging from the pulley, then the ideal MA is 2 .

How do Pulleys help?
Pulley used for change direction of the force, e.g. pull the weight up is change direction form pulling up to pulling down. Pulley arrangement can use to reduce the load require to lift object, e.g. fix rope to wall and put load hanging on pulley and pull 1 end so the wall support half of the load. See link for more detail.
A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. Determine final speed after mass 1 falls 4.5m?
A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. The final speed after mass 1 falls 4.5m is approximately 6.6 meter per square second.
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.

How do you design a machine to lift 2kg of mass with only 1kg of effort force?
First of all, "1 kg" is a mass, not a force. But we'll let that pass for right now, and move on to answering the question. Twice. 1). Set up a miniature see-saw. Place the pivot 1/3 of the way between the ends, so that the one end of the see-saw is double the length of the other end. Set the load on the short end, and push down on the long end. The force it takes to lift the load will be 1/2 the weight of the load. 2). Fasten one end of a rope to the ceiling. Pass the free end of the rope through a pulley, and hold the free end up so the pulley doesn't fall off. Hang the load from the pulley, and slowly lift the free end of the rope. The force on the free end that you need to lift the load will be 1/2 the weight of the load.
