The 2-kg rod AB moves up and down as its end slides on the smooth contoured surface of the cam, where r = 0.1mand z = (0.02sin(theta))m. If the cam is rotating at a constant angular velocity of 5 rad s, determine the maximum and minimum force the cam exerts on the roller at A. Neglect friction at the bearing C and the mass of the roller.
