A gear ratio has two types of gears: a driving gear and a driven gear. Which of the following is the best definition of a driven gear?
It turns first.
It is turned by the driving gear.
It is always smaller than the driving gear.
It is always larger than the driving gear.
Which of the following best describes a gear ratio that has the mechanical advantage of torque?
The driving gear is larger than the driven gear and speed is increased.
The driving gear is smaller than the driven gear and speed is increased.
The driving gear is smaller than the driven gear and power is increased.
The driving gear is smaller than the driven gear and power is increased.
True or False: The M.A.D. Box can show both speed and torque advantages at the same time.
True
False

None of these answers is correct.
A gear ratio is calculated by dividing _____
the number of the driven gear teeth by the number of driving gear teeth. In other words, input on output.
the number of the driving gear teeth by the number of driven gear teeth. In other words, output on input.
the torque by the speed.
None of these answers is correct
