A comparison of the number of teeth of one gear to another.

• gear total

• gear purpose

• gear ratio

• gear teeth number

Movement in a circular motion

• Rotary 
• Oscillating
• Linear
• Reciprocating

The gear train in which diagram provides more torque?

• A
• B

Which gear train would you use to apply the force necessary to ride up a hill?

• A

• B

The input gear has 6 teeth.
The output gear has 48 teeth.  The gear ratio is...

• 1:8
• 8:1
• 6:48

What is the BEST explanation for a gear train with a 7:1 gear ratio?

• The drive gear turns 1 time for every 7 turns of the driven gear.

• The driven gear turns 7 times for 1 turn of the drive gear.

• The gear goes fast!

When gears are equal in size, what is the gear ratio?

• 1:2
• 1:3
• 2:5
• 1:1

If the small gear is driving the large gear, what is happening to the torque?

• Torque is increasing

• Torque is decreasing

• Torque remains constant

• Not enough information to answer the question

The image shown is a vice grip.  When the lever is rotated, the grips move towards each other.  What are the input and output motions?

  output=linear
• input=linear
  output=reciprocating
• Input=rotary
  output=rotary
• Input=rotary
  Output=linear

What is the name of this mechanism?

• Simple Gear Train
• Gear Train with Idler
• Worm and Wheel
• Rack and Pinion
