The ideal mechanical advantage is calculated as:
Ideal_Mechanical_Advantage = distance_moved_by_effort / distance_moved_by_load.
It is ideal because it ignores real world factors like energy lost through friction.
So an Ideal Mechanical Advantage (IMA) of 7 means that the machinery amplifies the applied effort by 7.
For example, a 7 kg load can be balanced using a block-and-tackle arrangement (which has 7 ropes supporting the load block and thus an IMA of 7) using only 1 kg and lifted by applying slightly more than 1 kg.
In the real world, there is friction between the pulleys and their bearings so that more real effort is required before the load moves and the real Mechanical Advantage of the above block-and-tackle arrangement is less than 7.

How do you calculate the mechanical advantage of a pulley system?
The mechanical advantage is the ratio of the distance your hand moves to the distance the piston travels. For instance, if the lever is 21" long and a full rotation of the level produces a piston travel of 7" then your hand would move 2*pi*21" (131.9"). The ratio 131.9:7 reduces to 18.8:1. If you wanted to produce 1 ton (2000 lbs) of force on the piston you have to appy 106 lbs on the 21" lever.

Why the bridge rectifier is best?
What is the advantage of using the bridge rectifier A: NONE no advantage the only advantage can be considered it the fact it will provide more voltage but never more power actually less by a .7 volt diode drop
What is the ideal mechanical advantage of a lever 7 meters long and 3 meters high?

What is the ideal pH to grow wheat?
A pH of around seven (7) is ideal.
What effort force would be needed to lift a load of 150 N with a lever system that has a mechanical advantage of 3.5?
Well lets see. I suppose that a ballance is a lever advantage of one: which of course is the same on both sides; that is no advantage. So a lever of an advantage of two, is, half of that same force on the other side. So the answer is (half of 150) or 75N.
What is the ideal focus group size?

Which mechanical pencil lead equals a number 21 regular pencil?
A o.7 mechanical pencil will do the job.
What lever would have more mechanical advantage than one with a resistance are of 3 inches and an effort arm of 6 inches?
A lever with a longer effort arm and a shorter resistance arm would have more mechanical advantage. In this case, if you increase the effort arm to 7 inches while keeping the resistance arm at 3 inches, the mechanical advantage would increase. This is because a longer effort arm allows for less force to be applied to overcome a greater resistance.
