Simple machines don't measure anything. All six simple machines, invented by Archimedes, are used to make physical work easier.
A lever is a simple machine that allows mechanical force to be exerted using a varying distance. Typically, the lever allows the use of a smaller force across a greater distance in the place of a larger force over a smaller distance.

If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
Force - yes - a crowbar Distance - yes - high gear on a bicycle Energy - no.
A machine decreases the amount of force needed to work, as it distributes the force throughout a larger distance.
Force
yes. yes. no
A simple pulley can be used just to alter the direction of the force without multiplying it (although compound pulleys can also be used to multiply force).

The mechanical advantage of the machine is"if you give small accelration , it will increase the speed of the engine... It is possible by mechanical

That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.
