A wheel W of radius RW = 7 mm is connected to point O via the rotating arm OC, and it rolls without slip over the stationary cylinder S of radius RS = 15 mm. If, at the instant shown, θ = 47° and ωOC = 3.5 rad/s, determine the angular velocity of the wheel and the velocity of point Q, where point Q lies on the edge of W and along the extension of the line OC.
