Understanding Gears and Torque

What is the primary function of gears in machines?

• To provide stability

• To reduce noise

• To enhance efficiency

• To increase speed

What two components make up torque?

• Speed and distance

• Force and distance

• Mass and velocity

• Pressure and area

Why is it easier to push a revolving door further from the pivot point?

• The door is smaller

• The door is lighter

• The pivot point is stronger

• Less force is needed

How does the size of a gear affect the torque it provides?

• Larger gears provide less torque

• Gear size does not affect torque

• Larger gears provide more torque

• Smaller gears provide more torque

What is a sprocket in the context of bicycles?

• A type of wheel

• A special gear used with a chain

• A type of pedal

• A type of brake

In the race scenario, why did cyclist one struggle on flat terrain?

• The bike was too heavy

• The cyclist was tired

• The sprocket was too large

• The sprocket was too small

What advantage did cyclist two have with a smaller sprocket?

• More stability

• Easier uphill climbs

• Better control on turns

• Higher speed on flat terrain

Why did cyclist two struggle on the uphill section?

• Poor bike condition

• Inadequate training

• Insufficient torque

• Lack of speed

What is the trade-off when using a larger gear?

• More speed, less control

• Less torque, shorter distance

• More control, less speed

• More torque, longer distance

What lesson can be learned from the race about gear selection?

• Smaller gears are always better

• Always use the largest gear

• Gear size does not matter

• Gear selection depends on terrain
