Exploring the Mechanics of Simple Gears

What term is used to refer to the gear where power is input?

• Last gear

• Driven gear

• First gear

• Drive gear

What happens when gears of two different sizes are used?

• There is no impact on the gear system.

• The speed and torque remain constant.

• The gear system stops working.

• The gear ratio changes, affecting speed and torque.

What is the role of the input gear in a gear system?

• It only determines the direction of rotation.

• It has no specific role.

• It is where power is applied to the system.

• It receives power from the output gear.

How are speed and torque related in a gear system?

• Inversely proportional

• Both increase together

• Not related

• Directly proportional

What is the gear ratio when using two gears of the same size?

• 1:2

• 2:1

• 1:1

• Variable

What does a one-to-one gear ratio imply about the system's speed and torque?

• Both are doubled.

• Both are halved.

• Both remain constant.

• Both become zero.

Can the direction of travel in a simple gear system be reversed?

• Yes, but only if the gears are the same size

• Only in specific cases

• No, never

• Yes, always

Is the flow of power in a simple gear system reversible?

• Only with same-sized gears

• Never

• Depends on the direction of travel

• Always

What changes when a 60-tooth gear is replaced with a 12-tooth gear?

• The gear system becomes non-functional.

• Nothing changes.

• The direction of gear rotation reverses.

• The gear ratio changes, affecting speed and torque.

What happens to the output gear's speed when the gear ratio is 5 to 1?

• It increases fivefold.

• It becomes unpredictable.

• It decreases by five times.

• It remains constant.
