Rack and Pinion

Questions

1. What is the type of input movement? (rotary or linear)

2. What is the type of output movement? (rotary or linear)

3. Label the rack gear and the pinion gear

4. If the diameter of the pinion gear were increased, would the rack move a shorter or longer distance with one revolution of the axle?

5. Is the flow of power reversible? (Can you make the input shaft turn by sliding the output shaft?)

6. Is the direction of travel reversible? (Does the mechanism still work if the input shaft is turned in the opposite direction?)
