eLearning Lesson 2 by Millie Thng (07)

Part 1

1) Correction tape (back view)
When the smaller gear rotates in clockwise direction, the bigger gear will rotate in clockwise direction too as there is a belt linking both gears together. This lets the process flow smoothly as one simple movement can allow tape to "come out" and be used while at the same time transferring the "waste"  away

2) Kinder Joy toy
As the wheel rotates, the linkage between the wheel and the flashlight causes the rotary motion to be converted into reciprocating motion. When the toy is moved fast, it will seem as though the flashlight is flickering

3) Music box
When the crank is turned, the rotary motion is converted to another rotary motion which causes the gear to rotate and make music

Part 2

Problem : It is difficult to take things from the medicine cabinet as there is a basin in the way
Solution : To use crank and slider linkage to slide the shelf out
