Robotics Gear Trains and Motion Quiz

What is the primary effect of connecting a large gear to a small gear?

• Increases speed

• Decreases torque

• Decreases speed

• Increases torque

What does it mean when gears are 'meshed'?

• They are connected by a chain

• Their teeth are interlocking

• They are of the same size

• They are placed side by side

What happens to torque when speed is increased in a gear train?

• Torque increases

• Torque decreases

• Torque remains the same

• Torque fluctuates

What is the effect of using a small input gear and a large output gear?

• Decreases torque

• Increases speed

• Decreases speed

• Increases torque

What is the inverse relationship in gear trains?

• Speed and distance

• Torque and speed

• Size and weight

• Input and output

How do you calculate the gear ratio using the number of teeth?

• Divide the number of teeth on the input gear by the output gear

• Multiply the number of teeth on both gears

• Divide the number of teeth on the output gear by the input gear

• Subtract the number of teeth on the input gear from the output gear

What is the benefit of using the number of teeth over diameter for calculating gear ratios?

• It is more accurate

• It is easier and requires no tools

• It provides a larger ratio

• It is faster
