Work can be very hard and we need a lot of energy for it sometimes. This is why we often use tools and machines. How can a lever make our work easier? Teacher
I am glad you are here. This means that you are doing some extra English work at home. Our blog is just another way of communication between us. My plan is to post tasks here for you from time to time. It will not take much of your free time, but I hope it will help you improve your command of English. Your commitment will also be awarded according to our agreement at school. I want you to communicate in English. Do not forget to be polite and always sign your comment with your code; "anonymous" posts are not welcome. Teacher

Just an example: You need less effort for lifting things, but the amount depends on the distance from the fulcrum.
If you use leveler instead of your bare hands, you can lift up cargo much easier and more.
you don't need to be strong, you just have to use your head. Like the legend of Aristotel, who had lifted the whole ship with a hand
Can you retell the legend?

I read this definition of what simple machines are.
Here it is: ''a simple machine is any device that only requires the application of a single force to work.''
The question was about something else, Matjaž.
