Ideal Mechanical Advantage (IMA)
In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
In an ideal machine, if you exert an input force over a greater distance than the output force, the input force will be smaller than the output force. This is because work input is equal to work output in an ideal machine, and work is calculated as force times distance. Therefore, if the input force acts over a greater distance, the output force must be larger to balance the work done.
In an ideal machine, the input force will be smaller than the output force when the input force is exerted over a greater distance than the output force. This is because work input and work output must be equal in an ideal machine, and since work = force x distance, a smaller input force over a greater distance will result in a larger output force over a shorter distance to maintain equilibrium.

If the machine were ideal ( 100% effiency) the output force would be 300 N In practice you might get 250 - 270.
Mechanical Advantage=1
The actual mechanical advantage of a machine is usually less than its ideal mechanical advantage due to factors like friction, energy loss, and imperfections within the machine. These losses reduce the efficiency of the machine in transferring input force to the output force. Ideal mechanical advantage is based on the design and geometry of the machine, while actual mechanical advantage accounts for real-world limitations and performance.
The force required to overcome friction between parts of a machine or device causes a difference between the ideal and mechanical advantage of the object. Friction reduces the efficiency of a machine by causing energy losses, making it harder to achieve the theoretical ideal advantage.
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
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.
A real machine is like an ideal machine in that there are no massless chains or frictionless bearings. The parts of an ideal machine are rigid and weightless.
