Pulley's mechanical advantage??????
Only 1/4 of W is required to support the W in this system, or The input force we apply becomes x4 at the output. Thus the mechanical advantage is 4.
The number should be n>1 or it's never an "advantage"
Translating to English; Please let us know if this translation is wrong
A pulley system of negligible weight & friction is shown in the figure.
Find the x of the pulley system
x = (EnergyOutputByTheSystem / EnergyInputToTheSystem) x 100
subodhacharles Here's the problem in Sinhalese. Those assumptions are required even though they are not mentioned here
That object P must be replaced by the force applied
