Mechanisms Review

3. Allows power to be easily transferred over long distances
6. The metal rod which can spin
8. The number of teeth on the output gear compared to the number of teeth on the input gear
10. The gear which IS directly connected to the motor/power source
13. Output motion is reciprocating motion
17. Two gears with interlocking teeth
18. Output is oscillating motion
19. Output motion is linear but direction of power is not reversible
20. Motion which moved back and forth- no difference between being in “reverse” or “forward” mode
22. Speed and torque are constant but the angle can be changed up to 70 degrees

1. The number of times an axle spins in a second or minute
2. When one part causes the other to move
4. Two gears with interlocking teeth and axles making 90 degree angle
5. Force which is applied at an angle
7. The gear which is NOT directly connected to the motor/power source
9. Motion of turning in a circle
11. Increases torque a LOT, direction of movement is reversible but direction of power is not
12. Where the energy of a mechanism begins or
14. Motion of moving in a straight line
15. Motion which shifts between a start position and moving in a pattern that is not necessarily just back and forth
16. Turning a gear causes a straight piece with teeth to slide in a linear motion
21. Where the energy of a mechanism ends or leave the system
