Lesson details
Key learning points
- Cams usually convert rotary motion into linear motion.
- Rotary motion is movement that goes round.
- Oscillating motion is moving to and fro around a pivot point, as in a lever.
- Reciprocating motion is a backwards and forwards movement in a straight line, as in a slider.
Keywords
Cam - a mechanism that changes one type of movement to another
Rotary - movement that goes round in a circle
Linear - movement in a straight line
Reciprocating - backwards and forwards movement in a straight line, as in a slider
Oscillating - moving back and forth along a curved path
Common misconception
All cams create the same movement.
The size, shape and position of a cam will create different types of movement.
