eLearning Lesson 2 by Elijah_Wong (21)

Part One (1st, 2nd and 3rd Pictures)

1) The cupboard have linkages. This mechanism allows the cupboard to open and close it with lesser force

2) The wine-bottle opener is made up of gears. When both handles are pushed down, the screw attached to the wine cork will be pulled open.

3) The tap is a lever. This mechanism allows the tap to open with less force for water to be pumped.

Part Two (3rd and 4th Pictures)

One problem I encounter is the table. The table will not balance properly when heavy things are put onto it. It will not be stable and will cause the objects on it to topple of the table.

A solution to solve this will be using linkages. (As shown in the sketch) The adding of linkages allow it to be more firm and less likely for heavy objects to topple of when it is on the table.
