Types of Gears (Part 2)

What are gears typically made of?

• Wheels with teeth

• Smooth wheels

• Rubber bands

• Flat plates

What is a gear train?

• A type of pulley system

• Many gears joined together

• A pair of gears

• A single gear

What is the main advantage of gears over a cross belt pulley system?

• They are easier to install

• They prevent slippage

• They are quieter

• They are cheaper

What happens when two different sizes of gears mesh?

• They produce noise

• They create mechanical advantage

• They stop moving

• They slip

What is the main purpose of spur gears?

• To transmit power and motion between parallel shafts

• To reduce noise

• To change direction

• To increase speed

What is a key characteristic of helical gears?

• Teeth are straight and parallel

• Teeth are inclined at an angle

• They are used in car steering systems

• They produce a lot of noise

What is the main function of bevel gears?

• To reduce noise

• To shift power from one direction to another

• To increase speed

• To prevent slippage

What is a worm gear used for?

• To increase speed

• To reduce speed and give more power

• To transmit power between parallel shafts

• To change circular motion to linear motion

What does a rack and pinion gear do?

• Prevents slippage

• Changes circular motion to linear motion

• Increases speed

• Reduces noise

Where is a rack and pinion gear commonly used?

• In bicycles

• In car steering systems

• In computers

• In clocks
