Ch 8 Part 2

The magnitude of the force multiplied by the distance it is from the center of rotation (Force x Distance).

• Rotational Speed

• Torque

• Transmission

• Mechanical Advantage

In order for two gears to mesh, they need to have the same size (and shape) teeth on the same spacing.

• Gear Ratio

• Gear Pitch

• Gear Rack

• Gear Bearing

The relationship between the numbers of teeth on two meshing gears used to transmit motion. It reflects the change in mechanical advantage resulting from the gears.

• Gear pitch

• Tooth decay

• Gear ratio

• aspect pitch

The ratio of output force to the input force applied to a mechanism is known as ___________________.

• Pressure

• Weight

• Mechanical Advantage

• 3.14

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

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 transference of force between machines or mechanisms, often with changes of torque and speed.

• Optimism

• Idle

• Transmission

• Pitch

BIG gears are used for

• More turning power (torque)
• More rotational speed

LITTLE gears are used for

• More turning power (torque)
• More rotational speed
