Elearning Lesson 2 - Tam Wai Hang

Photo 1: Nail Clipper

The nail clipper is an example of class two lever and reduces the effort needed to use the nail clipper.

Photo 2: Pen Clip

The clip can be attached to another objects. It is another example of a class 2 lever.

Photo 3: Correction Tape

The gears are present in the correction tape to roll out the tape contained in it.

One problem present in the household is the shoe racks are placed below the chairs (Can be seen in photo 4). This makes in hard to get the shoes when one has to bend down to get their shoes. I suggest using a slider to pull the shoe rack out to get the shoes.
