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.

No relation. Mechanical advantage is a ratio (between the force applied to the mechanism and the external force provided by you ). Efficiency is the fraction of energy actually useful after taking into acount frictional losses etc.

The "ideal mechanical advantage" makes some simplifying assumptions, mainly that there are no losses, for example, due to friction. If there ARE losses, this will reduce the real mechanical advantage.
Mechanical Advantage is the number of times a machine increases the input force. Efficiency is the ratio of output work to input work.
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.
Ima is Ideal Mechanical Advantage and Ama is Actual Mechanical Advantage. The difference is that IMA doesn't take into account elasticity or friction and AMA does.
the equation of mechanical advantage isFout (force, output)divided byFin (force input)the equation for Ideal mechanical advantage isDin (distance, input)divided byDout (distance, output)hope this helps a bit
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum

Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.

No. That ratio is 'efficiency'.

An electronic stopwatch gives a higher accuracy than a mechanical stop watch.
no difference
In theory there is no difference in efficiency (it would be 1), but in practice I think a block and tackle would lose more force to friction in the pulleys and between the rope and pulleys.

absolute cost advantage talks about the efficiency and cheaply a country incure in the production of goods and services against other country whiles comparative advantage talks about the opotunity cost of goods
