Question

2. Emma squeezes the hand brakes of her bicycle

with a force of 60N. If the brake pads push on the
wheel with a force of 300N, what is the mechanical
advantage of this bike's brake system?

Answer 1

5N

Explanation:

The equation for mechanical advantage is:

`Mechanical \ Advantage = (F_o)/(F_i)`

Where "o" stands for output force and "i" stands for input force. Plug the given values into the equation:

`Mechanical \ Advantage=(300N)/(60N)=5 N`

The mechanical advantage is 5N
