Yes, it is exactly that.
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
Areas
It never referred as ratio but Rather a gain A in the form of output divided by the input and implies voltage A=gain. basically is input resistance divided by the feedback resistance
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
output/input
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
efficiency
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
This is called the mechanical advantage. and is just a ratio comparing how much you put in to how much you get out.
