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.

eLearning Lesson 2, Task 2 by Naveena Menon (4)

The problem identified: The door is heavy and whenever guest come, someone has to stand and prop open the door. This is tiring and difficult for some people as the door is quite heavy and they may not have enough strength. It is also hard to hold the door open if you are carrying stuff. Hence, there should be connections to the wall and the door on both the top and the bottom of the door. These connects would have hinges and a locking mechanisms (shown in drawing) and so the door would be able to be kept propped open without any external force.

Picture 1: The step of the dustbin acts as a lever. When it is stepped on, the top will open.
Picture 2: The hinges at the sides of the door of the microwave allows the microwave to be opened and closed.
Picture 3: There are grooves with rollers allowing the glass doors to be slid back and forth.
