What uses a rope and a wheel to move an object?
The pulley.
What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up
How does energy flow when a pulley is used to lift a box?
When the pully is not active, it is using potential energy. But when a person or a machine uses the pully, they use force to make Kinetic Energy and to lift the box....but that's what i know so far...but i . :)
What are the uses of a single pulley?
AnswerA single pulley can change the direction of a pulling line. The direction change may help in pulling the line over a corner or around an obstacle. Or the direction change may allow better use of the available pulling force. Also, the single pulley can relocate the pulling point.For example, suppose we wish to lift a weight some distance into the air. If I am the pulling force, then my first problem is that I cannot lift the weight any higher than I can reach. But if the pulling line is looped over a pulley some distance above my head, relocating the pulling point, I can potentially lift the weight just about up to the pulley's height. And now the pulley has given me another advantage. I can leverage my own weight, pulling down on the line, to lift the weight upward.
If a person tries to lift a heavy box for 5 seconds and can't make it budge the work done on the box is equal to the amount of energy the person uses?
true or false if a person tires to lift a heavy box for 5 seconds and can't make it budge,the work done on the box is equal to the amount of energy the person the person uses.
What is one disadvantage of using pulleys?
A pulley uses leverage to displace the pressure of an object, making said object easier to lift
Could a small person lift a heavy person?
Yes, if a small person uses a machine, like a lever or a pulley, to lift a person of more mass than the smaller person.
What simple machine uses grooved wheels and a rope belt or chain?
A pulley is a simple machine that has a grooved wheel that holds a rope or a cable. This is used to lift heavy loads. It is also known as sheave or drum.
What machine uses a pulley?
A block and tackle. an ellevator, a winch,
What uses a rope and a wheel to move an object?
The pulley.
Uses of single pulley?
it can help by pulling heavy loads using a rope
What are pulleys used?
removing genital warts aka jamesman pulleys are things that lift up thing in a less painfull waya mechanical advantage as far as liftingin wellsElevators, cranes, vacuums, and motors of all types, just to name a few.elevatersa pulley is use to lift loads, apply forces, and transmit power.to make work easier and to lift thing heavier than you and moveable pulleys are used the zipline and cloths lines but what in comes done to is it is a simple machine. answer improved by:kidwhoanswersyou use a pulley to lift a car engineA pulley can be used in a number of ways. The most common use of a pulley, however, is when one needs to lift large, heavy objects, usually with a truck or other large vehicle.the uses of pulley is to carry things above and below and to make distribution of things easier.Pulleys afford a mechanical advantage in, for example, the lifting of heavy or awkward loads to various heights. While pulleys are not particularly efficient (energy is lost to friction, and the pulleys and cables/ropes add their own weight to the load lifted), they allow the application of a lesser force over a greater distance.The effect of a pulley is analogous to the gears of a bicycle; a lower gear makes it easier to turn the pedals, but they must be turned more often for the bicycle to travel the same distance. Likewise, a pulley system makes it easier to lift a load, but the length of cable used to lift the load is greater than the distance the load is lifted. The more pulleys that are used, the easier it is to lift the load, but the longer the length of cable needed to lift the the same distance.Examples of pulley usage in the real world include:- lifting heavy machinery, materials, and tools to heights at building sites.- hoisting patients between a bed and wheelchair using a sling attached to pulleys, allowing the task to be undertaken by a single person.whatpulley is made of picking something upA pulley is a big wheel. It is easier to pull a rope down that to lift something up. Thus, it is easy to attach a rope to a heavy object and throw the rope around the pulley. Then you pull down on the rope. The heavy object goes up.It is used to pull things up or downThe pulley is currently used to easily lift items and objects.

More information of uses of pulley?
Pulley systems are used in the real world to lift large masses onto tall heights. You might have seen the workers repairing the roof of a house and using the pulley system to lift their tools or materials to the roof. A pulley is an example of a simple machine.The pulley system consists of one or more pulleys and a rope or a cable. The number of pulleys used may increase or decrease the mechanical advantage of the system. Generally, the higher the mechanical advantage is, the easier it is to lift the object that is being lifted.Overall, no matter how easy it is to use the pulley system, the system itself is not very efficient due to the force of friction. For example, one has to pull two meters of rope of cable through the pulleys in order to lift an object one meter.The applet below illustrates just that. Select the number of pulleys and drag the mouse to see the inefficiency of the system.
What are pulleys used for?
Eg volkswagon has a timing belt and a pulley tensioner that make the car run if they go your car won't work. They are supposed to be replaces every 100000km and when you replace one you replace both of them along with the watercpump because the labour is expensive and you don't want to have to pay to do it again in a month
What is a chain fall?
A block and tackle (pulley system) that uses chain to turn a cogged wheel. This permits lifting of extremely heavy loads.
How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
