*16–8. If gear A rotates with an angular velocity of WA = (0A + 1) rad/s, where 0, is the angular displacement of gear A, measured in radians, determine the angular acceleration of gear D when 0, = 3 rad, starting from rest. Gears A, B, C, and D have radii of 15 mm, 50 mm, 25 mm, and 75 mm, respectively.
