What is a gear train?

Back

A gear train is a series of gears that transmit motion and torque from one part of a machine to another, allowing for speed and torque adjustments.

Front

What is the purpose of using a gear train to ride up a hill?

Back

A gear train with a higher gear ratio provides more torque, making it easier to pedal uphill.

Front

What is gear ratio?

Back

Gear ratio is the ratio of the number of teeth on two gears that are meshed together, determining how much one gear turns in relation to the other.

Front

If the input gear has 6 teeth and the output gear has 48 teeth, what is the gear ratio?

Back

8:1

Front

What is torque?

Back

Torque is a measure of the rotational force applied to an object, often described as a force that causes an object to rotate around an axis.

Front

What are the two types of motion in a bike?

Back

Linear and Rotary motion.

Front

What happens to torque when a small gear drives a large gear?

Back

The torque increases.

Front

What is rotary motion?

Back

Rotary motion is the circular movement of an object around a central point or axis.

Front

What is linear motion?

Back

Linear motion is the movement of an object in a straight line.

Front

What is reciprocating motion?

Back

Reciprocating motion is a back-and-forth movement in a straight line.
