A compound machine is one in which ________________.

  1. a battery provides the force
  2. one simple machine rotates around the second one
  3. two or more simple machines work together
  4. the mechanical advantages can be made to balance each other out

When meshing or interlocking gears have different numbers of teeth, ______________.

  1. relative speeds depend on the speed of the drive aide for both
  2. both gears will rotate at the same speed
  3. the gear with more teeth will rotate fester than the gear with fewer teeth
  4. the gear with fewer teeth will rotate fester than the gear with more teeth

Answer(s): D

Explanation:

When meshing or interlocking gears have different numbers of teeth, the gear with fewer teeth will rotate faster than the gear with more teeth.
If two gears are meshed, both cannot be driven or something will break – one must be driving and one must be driven.



Cranks are used to ____________.

  1. convert motion in a circle into motion in a straight line
  2. convert motion in a straight line into motion in a circle
  3. attach to rotating shafts to push separate pieces in a given direction
  4. transfer power between rotating shafts of different diameters

Answer(s): B

Explanation:

Cranks are used to convert motion in a straight line into motion in a circle, such as in a bicycle's pedals and pistons in an automotive engine.



Which of the other gears is moving in the opposite direction from Gear 1?

  1. Gear 2
  2. Gear 3
  3. Both Gears 2 and 3
  4. Neither Gear 2 or 3

Answer(s): A

Explanation:

Meshed gears turn in opposite directions. Gear 1 is turning clockwise; therefore.
Gear 2 is turning counterclockwise (the opposite direction from Gear 1) and Gear 3 is turning clockwise (the same direction as Gear l).



Force is something that can change the velocity of an object by making it ________________.

  1. start or stop
  2. speedup
  3. slow down
  4. all of the above

Answer(s): D

Explanation:

Force is something that can change the velocity of an object by making it start or stop, speed up, or slow down.
