A lever used to lift a heavy box has an input arm of 4 meters and an output arm of 0.8 meters. What is the mechanical advantage of the lever?

The mechanical advantage of the lever is 5, meaning it multiplies the input force by a factor of 5. ;

The mechanical advantage formula of lever is:
MA Lever = Fo (output force of lever) / Fi (input force)
=> We usually lever to make our work easier in lifting objects. In this given situation, we need to find the mechanical advantage of a lever.
Given numbers:
=> Input arms = 4 meters
=> output arms = 0.8 meters
Now, let us solve by dividing the output arms and the input arms.
=> 0.8 meters / 4 meters
=> 0.2 meters
Thus, the mechanical advantage of lever is 0.2 meters.

The mechanical advantage of the lever is 5, calculated by dividing the length of the input arm (4 meters) by the length of the output arm (0.8 meters). This indicates that the lever can lift an object with a force 5 times the input force. Therefore, it significantly simplifies the task of lifting heavy objects.
