The flat circular disk rotates about a vertical axis through $O$ with a slowly increasing angular velocity $.$ Prior to rotation, each of the

$0\mathrm{.}59-$kg sliding blocks has the position $x=30mm$ with no force in its attached spring. Each spring has a stiffness of $490\frac{N}{m}.$

Determine the value of $x$ for each spring for a steady speed of $209re\frac{v}{m}in.$ Also calculate the normal force $N$ exerted by the side of the

slot on the block. The force N is positive if it pushes from the side labeled A $.$ Neglect any friction between the blocks and the slots, and

neglect the mass of the springs. $($Hint: Sum forces along and normal to the slot.$)$
