How much weight does a fixed pulley take?
A fixed pulley does not take any weight itself. It redirects the force applied to it, making it easier to lift a heavy object by changing the direction of the pull.
How much weight can a pulley lift?
The amount of weight a pulley can lift depends on factors such as the design of the pulley system, the strength of the rope or cable used, and the efficiency of the pulley itself. However, a single fixed pulley does not provide any mechanical advantage and can only lift as much weight as is being applied to it.
How is a window an example of a pulley?
The blinds that cover windows are often operated by a pulley. In order to pull up the blinds, one needs to pull down on rope attached to a pulley that changes the direction of the applied force so that a downward pull causes an upward push of the blinds. Although the window blinds are on a pulley system the window itself is not an example of a pulley.
Does weight affect a pulley?
Yes, weight has a huge effect on a pulley system. The amount of weight being moved or lifted directly affects how well the pulley works, and too much weight can break it altogether. Weight is also the main leverage in a pulley system.
How much effort is exerted if the weight is 400 grams and the pulley used is a movable pulley?
For a movable pulley, the effort required would be half of the weight being lifted. So with a weight of 400 grams, the effort exerted would be 200 grams. The movable pulley helps distribute the load, making it easier to lift the weight.

How much weight can a reindeer pull?
Depending on the age, a bull can approx. pull twice its own weight!
How much can a pitbull pull?
How much a pitbull can pull will vary greatly depending on his or her size and weight and conditioning. On average, a dog can easily pull 3 times his or her weight on wheels.
What is a fixed pulley used for?
In a simple case of lifting a weight using a pulley, there are two ways to do it and two different results. First, attach a pulley to the ceiling, and a rope to the weight which is on the floor. Run the rope through the pulley. Now we simply pull down on the rope and the weight is lifted up. In the second case, we attach one end of the rope to the ceiling, the pulley to the weight, and pass the unattached end of the rope through the pulley. Now we have to pull the rope up, and the weight is lifted. Now let's look at each job and what happens. In the first case, pull the rope tight without lifting and hold the rope at the top, next to the pulley. If you now pull the rope all the way down to the floor, the weight goes all the way up to the ceiling. Note also that the tension in the rope is equal to the weight being lifted and that there is only one tensioned rope pulling the weight upwards. Passing over the pulley changes the direction of the tension in the rope but doesn't change it's pulling power. Pulling that rope from ceiling to floor is exactly the same as lifting the weight from floor to ceiling. In the second case, tighten the rope before lifting and hold the rope where it exits the pulley on the weight. Now pull and your hand moves from there to the ceiling - about the same distance (but the other way) as you moved your hand in the other case. However, notice now that the weight is only half way to the ceiling. It is hanging on a loop of rope, one side going to the hook and the other going to your hand. This suggests that the weight is shared by these two parts of the rope and therefore the tension in each piece only needs to be half the weight. Your hand is holding half the weight. The ceiling hook is still holding the other half. To finish the job, you will have to keep pulling more rope - all the rope which is still there from hook to weight pulley and back to your hand. That's the floor to ceiling distance. In the second case, you pull twice as much rope to finish the job. And because it takes twice as long, it only needs half the force at any stage.

Which pulley system can make work easier?
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
How much effort is exerted if the weight is 400 grams and the pulley used is a movable pulley?
For a movable pulley, the effort required would be half of the weight being lifted. So with a weight of 400 grams, the effort exerted would be 200 grams. The movable pulley helps distribute the load, making it easier to lift the weight.
What is the name of the pulley used to pull a bucket out of a water well?
The type of pulley used to pull a bucket out of a water well is typically referred to as a "well pulley" or a "well bucket pulley." This type of pulley is specifically designed for lifting objects out of wells and is often made of durable materials such as steel or iron to withstand the weight of the bucket and its contents. Well pulleys are commonly attached to a rope or chain system to facilitate the lifting process efficiently.
What is the significant benefit of a compound pulley system?
it is that a person does not ave to lift as much weight
