Scissor linkage: dynamic analysis

  1. Jul 26, 2011 #1
    Hi guys,

    I have a scissor linkage and I should calculate the force F for keeping the system in equilibrium in a specific position. The force must be applied in the the middle joint as you can see in the following picture:

    L is the arms lenght, instead a is the horizontal distance between the two joints. How can I calculate this force for a specific height and supported weight? Any suggestions, or links are appreciated.

    Thanks
