    thank you for your help.
    yes i was trying to figure out that.
    i am trying to project a volleyball throwing machine and getting knowledges about that. i need any different ideas. the two thing is to keep in mind that the ball will not rotate on its own center as much as possible and the trajectory is determined (specified)

    Not sure if you are trying to construct something for yourself or manufacture something, but if you are looking to make a simple ball hurling machine, do a Google search for Trebuchet. It is a simple style machine that you could use to hurl any type of object.
