Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
The mechanical advantage of a screw can be found by dividing the circumference of the screw by the pitch of the screw. In this case, the total mechanical advantage is equal to the circumference of the simple machine to which the effort force is applied divided by the pitch of the screw.

Mechanical Advantage is given by the following equation: MA = Load Effort On a class 2 lever, the fulcrum (pivot) is at one end of the lever and the work applied is at the other end. The load is then applied near the fulcrum, as common with the wheel barrow. A class 3 lever has the effort applied between the fulcrum and the resistance. Therefore, a much greater effort will be required to produce the same moment value. A typical C2 lever has a much greater distance in which to produce the load than a C3 lever.
From the design of the lever (on paper), the mechanical advantage is effort arm/load arm which means Distance from pivot to the applied force/distance from pivot to the load The result of that is that the forces will have the reciprocal ratio, and the input force to the lever will be the output force/the Mechanical Advantage .

if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.

it is d ratio of the load to the effort applied to move the load if mechanical advantage>1(ie L/E >1), the machine acts as a force multiplier otherwise as a machine to gain speed mechanical advantage is abbreviated as M.A.
The ideal mechanical advantage is determined by the shape, size, and configuration of the simple machine. The weight of the load, the size of the applied force, or the weight of the components or materials of the machine itself have no effect on the ideal mechanical advantage.
distance over which the force is applied ________________________________ Distance over which the load was moved or MA= Effort Force _________ Load force OR MA= Length of Load arm ____________________X Weight/mass Length of Effort arm
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
There is no mechanical advantage. It's a directional advantage. You change the direction of the force to be applied to your advantage, so you can use stronger muscles, a beast of burden, etc.
The mechanical advantage is that the force applied increases but that is compensated by the fact that the rope or chain needs to be moved through a greater distance.
