58 PROBLEM 16.18 A prototype rotating bicycle rack is designed to save space at a train station. The combined weight of platform BD and the bicycle is 40 lbs and is centered at 1 ft. above the midpoint of the platform. The motor at A causes the support beam AB to have an angular velocity of 10 rpm and zero angular acceleration at 0 30°. At this instant, determine the vertical components of the forces exerted on platform BD by the pins at B and D.
