1. What is a gear or cogwheel A rotating machine part
with teeth or cogs,
which mesh with anoth-
er toothed part to transmit
torque
2. What is torque The ability of a force to
cause rotation around an
axis.
3. What are two or more gears working in a sequence A train or a gear train
called
4. What can a gear train be considered and why A simple machine because
it can produce a mechan-
ical advantage through a
gear ratio
5. What is it called when two or more gears are touching Meshed
6. If the gears are touching, then the adjacent gears Opposite
move in ________ directions
7. When there are an ____ number of meshed gears, then Odd
the last gear will always turn in the same direction as
the first gear
8. Gears can change the ______, ______, and _______ of a Speed, torque, and direc-
power source tion
9. What is a non-rotating toothed part called and what is A rack; a translation in-
produced when a gear meshes with one stead of rotation

What happens when two gears mesh and one gear is A mechanical advantage is
bigger than the other produced and the rota-
tional speeds and torques
differ in an inverse rela-
tionship
11. What is the most simple type of gear and characteris- A spur gear
tics of it - Cylinder or disk with
teeth projecting radically
12. A belt and pulley system consists of ___________ con- two or more pulleys
nected by a belt
13. If the diameter of a pulley is double that of it's connect- It halves it
ed pulley, how does it affect the RPM
14. Diameter of pulley A / diameter of pulley B = 4/8, so 1/2
pulley B will run ____ as fast as pulley A.
15. Diameter of pulley C / diameter of pulley D = 4/16, so 1/4
pulley D will run _____ as fast as pulley C
16. What is a pulley A wheel on an axle or shaft
that is designed to support
movement and change of
direction of a cable or belt
along it's circumference
17. How are pulleys typically used To lift loads, apply forces,
and to transmit power
18. What is a sheave or a drum Another name for a pulley
19. What is the drive element of a pulley system
