The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
the spring does not have a mechanical adavantage because the amout of force you put in to it is the amoot of force that the spring provides. The real mechanical is that you can time when the force is provided
input force
The mechanical advantage of a spring is the ratio of the force exerted by the spring to the force applied to compress or stretch it. This ratio helps determine how much the spring can amplify or reduce applied forces in a mechanical system.
Real mechanical advantage is the ratio of output force to input force in a mechanical system, taking into account losses due to friction and other inefficiencies. Speed ratio, on the other hand, is the ratio of the speed of the output gear to the speed of the input gear in a gear system. Speed ratio does not take into account efficiency losses like real mechanical advantage does.
in the real world
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.
A real machine is a physical device that performs mechanical tasks in the physical world. It operates based on principles of physics and mechanics to convert inputs into outputs. Examples include cars, washing machines, and computers.
Friction is not typically considered when calculating the ideal mechanical advantage. The ideal mechanical advantage assumes no energy losses due to friction, but in real-world applications, friction can reduce the efficiency of a machine.

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
