Work done by load = work
done by effort A car jack is used to lift a heavy load. The lever attached to gear "A" travels through a distance of 4.45m when a force of 34N is applied. The load is lifted to a height of 0.50m. Assuming no friction, what is the maximum load that can be lifted by the 34N force? Work = force (applied) X distance moved Work(load)
= Work(effort) What type of gear system is this? Rack and pinion

Look at the image on the leftt. Gear "B" has 36 teeth and gear "A" has 12. Calculate the gear ratio of
this gear train if "B" is the driver. |
Look at the image on the right. Gear "B" has 12 teeth and gear "A" has 24. Calculate the gear ratio of
this gear train if "B" is the driver. |

The hand drill on the right uses intermeshing bevel gears. Gear "A" has 80 teeth while gear "B" has 16. Calculate the number of turns the drill bit will complete if the handle is turned through 2 complete rotations? |
 |
The gear train on the left is made up of the three gears. Gear "A" has 24 teeth while "B" has 8 and C has 16. What is the gear ratio of this gear train if "A" is the driver and "C" is the follower? For every clockwise turn of gear "A" calculate the number of turns and the direction of motion gears "B" and "C". |
| Refer to the gear train on the right. For every revolution of the driver gear calculate the number of turns of the follower.. |  |
