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.
