Lesson details
Key learning points
- Cams are used in mechanisms to change the direction of motion.
- Pulleys transmit rotary motion.
Keywords
Cam - a mechanical component that converts rotary motion into linear motion
Follower - a part of a machine that moves up and down or back and forth when it touches a cam
Friction - resistance which is encountered when two things rub together
Pulley - a grooved wheel over which a belt can run
Common misconception
The larger the diameter of a pulley wheel, the higher the output speed.
The smaller the pulley wheel, the quicker it will complete a rotation, therefore increasing the output speed.
