In our high school physics subject, we encountered different kinds of simple machines which are used to help us achieve our work efficiently. One of the best forms is the lever. By definition, a lever is a tool that uses a fulcrum to produce a maximum result with a minimum effort. Examples of levers are the hydraulic jack and the seesaw. In replacing a wheel, for instance, a hydraulic jack is used to lift the car. If the lever arm is longer, the effort needed becomes less.

hello
Hi Carl…
Thanks for the message… It is good to know that there are people who do no just give in to pressure selling and scams like this… I pity the poor fellows who got sucked into their system of creating ill-goten wealth.

Hi Edmund, nice topic, i think ca2020 is not living their mission, vision and motto. I felt relieved that you have exposed the company’s doings. It such a big disappointment and i literally dont recommend this company to anyone…
