Question

A input gear with 24 teeth is connected to an output gear with 12 teeth (Figure 9.13). a. If the output gear turns twice, how many times does the input gear turn? What is the gear ratio? What is the mechanical advantage? b. What is being multiplied in this gear combination, force or speed?

Answer 1

Answer:

If the 12-tooth output gear turns two times, the 24-tooth input gear turns one time. The gear ratio is 2 so the mechanical advantage is 1/2 or 0.5. Speed is multiplied in this gear combination.
