eLearning Lesson 2 by Stacey Yip (5)-Part 1

Part 1

Scissors

The scissors is a first class lever (whereby the fulcrum is in the center). It helps us to efficiently cut stuff by applying little effort.

  1. Correction tape:
    It uses gears to roll the used tape in and unused tape out. This effectively enables us to erase our mistakes.

    Hinge:
    This is a hinge from the door. It helps us to open and close the door.

    Problem: Walking up and down the stairs to retrieve small things is very troublesome.

    Solution: A pulley system with a bucket at the end to put the small things that was left downstairs.This works only if there is someone at the bottom to help you retrieve these stuff. Vice versa. This especially helps my grandmother as it is very troublesome for her to walk up and down just for small little things.

  2. Sorry about the weird posting... This post is a combination of part 1 and 2. The comment above is the continuation of the posting as it got chopped off when it was emailed.

    The first 3 pictures are task 1. The last two is task 2.
