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.


Do you use more force using 1 pulley to pull an object or 1 or more pulleys?

More force is exerted with one pulley.


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


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 is the advantage of adding pulleys to a pulley system?

More mechanical advantage.


a pulley system uses a 250-N force to lift a 2,740-N crate, What is the mechanical advantage of the system?

Answer: Mechanical advantage can be achieved just by adding more loops or pulleys. It is given that to lift a crate, a pulley system exerts a force of 2,740 newtons. It is required to find the mechanical advantage of the pulley system if the input force is 250 newtons What is the mechanical advantage of the pulley system if the exerted force changes from 2,740 newtons to 250 newtons? As if the force does some work, it increases the distance. Mechanical advantage does nothing with the number of pulleys. It only depends on the weight that is to be lift. Also, F1/F2 = 2740/250 = 10.96 The multiple pulleys create mechanical advantage. It can be achieved just by adding more loops or pulleys. Therefore, Mechanical advantage can be achieved just by adding more loops or pulleys.


What are some pulleys?

Simple pulley. Compound pulley. The reel is composed of two or more pulleys.


Where else are pulleys used?

assuming that your question is what jobs are pulleys used for... then the answer is any job that you need to lift something that is heavy. The pulley give a mechanical advantage when used together with other pulleys to apply more force to move the object

What is the importance of pulley?

pulleys allow you to lift significantly more weight than without them


When two kinds of pulleys are used together what is the system called?

When two or more pulleys are used together it is called a compound pulley system.


What pulley is attached to the load and moves as the load moves Hi I'm Gretchen?

Hi Gretchen, this arrangement to gain mechanical advantage is often referred to as a "block and tackle". It consists of pulleys and ropes, usually not more than four, where the pulley attached to the load moves with the load, and the mechanical advantage is determined by the number of ropes.
