Dynamics Coursework; Angular Velocity, Springs, Force

  1. May 2, 2012 #1
    1. The problem statement, all variables and given/known data
    The flat circular disc rotates about a vertical axis through O with a constant angular velocity of 240rpm. Prior to rotation, each of the 0.5kg sliding blocks has the position x=25mm with no force in its attached spring. Each spring has a stiffness of 400N/m, Neglect any friction between the blocks and the slots, and neglect the mass of the springs.

    (a) Determine the value of x for each spring
    (b) Calculate the normal force N exerted by the side of the slot on the block

    I have attached the diagram.

    2. Relevant equations
    Not yet completely sure. If someone knows of a resource towards rotational velocity, that would be helpful, but I will update this section as soon as I have identified appropriate equations.

    3. The attempt at a solution
    As per above, I will upload something as soon as I can get a solid attempt down. I'm honestly incredibly lost on this question, it just seems like there are so many aspects happening at once.
