Chapter 12, Problem 12.133RP

Disk A rotates in a horizontal plane about a vertical axis at the constant rate ${\stackrel{.}{\theta }}_0=10$ rad/s. Slider B has mass 1 kg and moves in a frictionless slot cut in the disk. The slider is attached to a spring of constant k, which is undeformed when $r=0$ . Knowing that the slider is released with no radial velocity in the position $r=500$ mm, determine the position of the slider and the horizontal force exerted on it by the disk at $t=0.1$ s for (a) $k=100$ N/m, (b) $k=200$ N/m.
