Input Distance is the distance the input force acts through.
yes. yes. no
Distance input = Mech Adv/Distance output
input distance- the distance the input force acts through
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
Yes. Yes. No.
output distance/input distance
The equation for ideal mechanical advantage is: Output force/input force, Or input distance/ output distance.
That's the "Input Work".
force * distance = work
Actual Mech. Advantage
That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
