Efficiency is the proportion of energy usefully used. Using a pulley system does not use less energy it just changes the ammount of force. Pulleys do have a small ammount of friction so having just one pulley would be more efficient. (but not much more)

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.
What were the advantages that the Northern military had over the Southern military during the US Civil War?
1. The North had a huge amount of industry, and was their way of life unlike the south who were agriculture. 2. North had a 3X larger population (more troops, and more people for war effort) 3. North had 2X more railroad systems, and the South's railroad system wasn't very efficient even. 4. North had the Navy, and they were able to blockade the South (operation Anaconda) 5. North had efficient tax system, unlike the South, were the state governors were reluctant to provide funds to Richmond. 6. After the capture of the Mississippi River the South was split and the Union held control of the river from New Orleans to St. Louis.
Why does the United States not use the metric system?
The metric system is generally considered superior to the imperial system due to its easy of conversion between units. For example: 10 millimeters = 1 centimeter 100 centimeters = 1 meter 1000 meters = 1 kilometer 1000 milliliters = 1 liter 1000 grams = 1 kilogram The smallest commonly used units in the metric system are alot smaller than those of the imperial system and can therefore make more accurate measurements with out needing to use fractions.
How efficient were World War 1 pistols?
They were fine as long as you kept them clean and dry although it would be hard to do that in a trench.
What were some positive impacts of government policy changes on business and industry?
Government policy changes have a gret impact on the workings of business and industry. 1.increases competition 2.market orientation 3.more demanding customers 4.increase in exports 5.efficient technology
Do you use more force using 1 pulley to pull an object or 1 or more pulleys?
More force is exerted with one pulley.
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
How much force will the operator have to apply if the mechanical advantage of the pulley system is 4?
1/4 the output force.
List three ways to run a application within the visual basic net environment?
1) Shell command 2) system launching commands (More efficient) 3) ...
What is mean efficient?
Definition of efficientadjective1(of a system or machine) achieving maximum productivity with minimum wasted effort or expense: more efficient processing of information[in combination] preventing the wasteful use of a particular resource: an energy-efficient heating system2(of a person) working in a well-organized and competent way: an efficient administrator
What is the generator pulley ratio when the crankshaft pulley is 6 inches in diameter and the generator pulley is 3 inches in diameter?
1:2
Which economic system is most efficient?
That's the 1 million dollar question which has no true answer, just opinion.
What is velocity ratio of a pulley?
The ratio for a simple pulley (not a pulley block), using an inelastic string, is 1.
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.
Why reciprocating air compressors need a belt drive?
They do not but the belt pulley system offers much in the way of mechanical advantage pump pulley often much smaller than motor or engine pulley means for every 1 rotation of motor 2 rotations of pump
Describe one advantage and one disadvantage of minimizing the number of lines of code you write c sharp?
It depends on what had been minimized. Example 1: int n = 1 + function(100); // assume function return an int value Console.Write("{0}, {1}", n, n + 100); vs Console.Write("{0}, {1}", 1 + function(100), 101 + function(100) ); Which one is more complex and which one is more efficient? (answer: 1-liner is more complex, yet 2-line code is more efficient) Example 2: int n = 1 + 100; Console.Write("{0}, {1}", n, n + 100); vs Console.Write("{0}, {1}", 101 , 201); Same question: which one is more complex, which one is more efficient? (answer: the 2-liner is more complex than it has to, the 1-liner here more efficient)
Which type of pulley has an ideal mechanical advantage of 1?
A single fixed pulley (:
