the question is asking for the ratio of the first gear to the second gear:
first gear:second gear=8:56
we can simplify this ratio:
8:56=1:7
so the correct option should be B

The force advantage of the direction changing pulley shown is 1. The correct option is b.
<h3>What is force advantage?</h3>
Force is the mechanical physical quantity. The force advantage is equivalent to the mechanical advantage equal to the ratio of output to the input force.
In the single fixed pulley, there is only one rope segment that pulls up on the load, so,
The force advantage is
F.A = 50 N / 50 N = 1
Thus, the force advantage of the direction changing pulley shown is 1. The correct option is b.

On or near the surface of the Earth, 1 newton is the weight of about 102 grams of mass.
Note that the gravitational force between the object and the Earth is always the
same. It doesn't matter whether the object is falling, flying, floating, fluttering,
rising, sinking, rolling, sliding, or just laying there. It doesn't change.
