No. You'll never see a bathroom scale that says your mechanical advantage
is 140 pounds.
The mechanical advantage of a device like a lever or a hydraulic jack is a measure
of how the force changes between the input of the device and its output.

What is the mechanical advantage of a machine that changes only the direction of applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.

Does mechanical advantage have the units of force?
No, mechanical advantage has no units, it is simple the ratio of an output quantity, such as force, to the input quantity. For example if it takes 10 pounds to lift a 50 pound object, the mechanical advantage is = 5
What is the formula to find mechanical advantage?
The mechanical advantage that a machine would have without friction or in another term is that you can find the IDEAL MECHANICAL ADVANTAGE (IMA) OF A MACHINE IS BY HAVING A MACHINE WITH NO FRICTION, ALSO BY MULTIPLYING YOUR EFFORT FORCE BY 2, HOWEVER BECAUSE OF FRICTION AND THE WEIGHT THE ACTUAL MA WILL BE LESS.
What is the mechanical advantage of a simple machine that requires a force of 40 newtons input to output 200 newtons?
The answer is 5. To find mechanical advantage, divide the force required by the force given. 200/40 = 5
How do you calculate the ideal mechanical advantage of a lever?
It's 1. IMA = Distance in / Distance out. A single pulley doesn't do anything toward mechanical advantage, it changes the direction of the force. Not always. A single-axeled pulley (the typical pulley) has an IMA of 1, having one axel. If there was a second axel, then the IMA would = 2, so on and so forth. The easy way to do it is IMA = # of axels.
Which is better a incline plane or pulley?
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.
How can two machines appear identical and yet not have the same actual mechanical advantage-?
They can't uless some parts are hidden from inspection.
What is the advantage to using 2 pulleys at the same time?
A single pulley normally gives no mechanical advantage: it changes the direction of the force required.With 2 pulleys the rope or cable is looped around both so that there are several lengths of it pulling the mass. If there are k such strands, each one bears 1/k of the total mass so (if you ignore friction) there is a mechanical advantage of k.____________________________________________The mechanical advantage of two pulleys mounted in a block and tackle is twice the applied force. The lead rope needs to have half the force applied to move the same load, but twice the distance must be moved on the lead rope such that the same total force is applied to the load.
How can a wedge be considered an inclined plain?
It provides mechanical advantage to an operation in the same way as does an inclined plane. That is, it multiplies force (at the expense of distance).
What is the difference between mechanical advantage and Efficiency?
A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force. This is compensated for by the fact that the distance moved by the input is greater than the output so that in an ideal machine, the work input (Force*Distance) is the same as the work output. In real life, though, you always lose some energy - in the form of frictional heat, or sound.A negative mechanical advantage is the opposite. A small distance moved by the input is converted to a large distance moved by the output. But the force in the output is correspondingly reduced.A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force.

Does the mechanical advantage MA depend on the actual mass lifted through the incline?
no the mechanical advantage does not depends on the mass of the object lifted throgh inclined plane because if we increase the mass then we have to increase the force to pull the object up and the ratio will remain same.
