Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
According to the laws of physics, output force (F) times output distance (D) equals output work (W). W = F x D
force output x distance = work output ~same for input
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
input distance- the distance the input force acts through
Output distance is.
fulcrum-output mass
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
According to the laws of physics, output force (F) times output distance (D) equals output work (W). W = F x D
output distance/input distance
force output x distance = work output ~same for input
The equation for ideal mechanical advantage is: Output force/input force, Or input distance/ output distance.
Work Output=Resistance X Distance
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
Distance input = Mech Adv/Distance output
