A pulley system has a mechanical advantage of 3, and an object weighing 9 Newtons must be lifted 15 meters. How much force must be applied to lift the object?
Use the following equation to find the answer:
MA=Fo/Fi

3 N
3 N
27 N
To find the force that must be applied to lift the object, we need to rearrange the formula for mechanical advantage (MA = Fo/Fi) to solve for the output force (Fo).
MA = Fo/Fi
Fo = MA * Fi
Given that the mechanical advantage (MA) is 3 and the weight of the object (Fi) is 9 Newtons, we can substitute these values into the equation:
Fo = 3 * 9
Fo = 27 N
Therefore, the force that must be applied to lift the object is 27 Newtons.
