If bar A moves right at a speed of x,how does bar B move?

    Hi..
    1. The problem statement, all variables and given/known data

    http://data.imagup.com/12/1146557882.jpg
    If bar A moves right at a speed of x,how does bar B move?

    2. Relevant equations

    speed of the gear(A) * number of teeth(A) =speed of the gear(B) * number of teeth(B)

    3. The attempt at a solution
    as A slide to the right, so the C gear will turn Clockwise (CW);the D Anti CW ,E CW;
    F anti CW so B will slide to the right.
    about the spped the B will slide slower than rank A :)
    thnks in advance.

    hi zizodev! :wink:

    yes, that's fine :smile:

    quicker wold be to count the number of gears …

    the are 4 circular gears, and 4 is even, so the first must go the opposite way to the fourth

    (and yes, B will slide to the right, slower than A … you still need to count teeth to find how much slower! :wink:)

    yes tiny-tim that's right...and the value is X/2 since the speed of the A=X.:)
