The FIrst YeAr AT ItP

After experiments, I decided to use lever mechanism and servo motor.

<<The principle of leverage>>

the point where you apply the force is called the effort. The effect of applying this force is called the load. The load arm and the effort arm are the names given to the distances from the fulcrum to the load and effort, respectively. Using these definitions, the Law of the Lever is :

Load arm X load force = effort arm X effort force.

There are three classes of levers(first, second, and third-class) which represent variations in the location of the fulcrum and the input and output forces. -Wikipedia-

A first-class lever is a lever in which the fulcrum is located in between the input effort and the output load. For the project, I use the principle of the first class lever.
