Appreciating Innovative Efforts in the Design of Machines to Simplify Work

 

1. Machines are simple tools invented by human beings to make work easier. We should be grateful to scientists and inventors who design and improvise machines to make our life easier and more comfortable.

 

2. Devices such as bottle opener, stapler, scissors, plier, paper cutter and so on are commonly used in our daily life. These devices simplify out work and we should appreciate these devices and use them with care.

 

3. Most of the machines we use today are compound machines, created by combining several simple machines. For example, a crane is made from a combination of many simple machines.
