Mechanical advantage is defined as the ratio of resistance overcomes to the effort applied. ... The efficiency of a simple machine is defined as the ratio of useful work done by a machine (output work) to the total work put into the machine (input work). For ideal or perfect machine, work output is equal to the work input.
The ideal mechanical advantage is the mechanical advantage of a machine with no inefficiencies. The actual mechanical advantage is the mechanical advantage of a real machine with all of the inefficiencies. ... The actual mechanical advantage is the ratio of the output force to the input force.
The parts of pulley system will cause the actual mechanical advantage to be less than ideal mechanical advantage is number of ropes and also the frictional parts
actual mechanical advantage Is the ratio of load and effort in an actual machine in which ther is loss of energy due to friction
Ideal mechanical advantage is when there is no loss of energy in other forms like heat, light, sound, but since practically this is impossible, actual mechanical advantage is always less than ideal mechanical advantage.
MA = Original Force/Reduced Force
MA = (36)/(0.6)
MA = 60
mechanical advantage (m.a) = w/p
= 50 lbs
= Output force / Input force
The parts of a pulley system that might involve friction will cause the actual mechanical advantage to be less than the ideal mechanical advantage.
