For the mechanism in the posture shown, the input arm, link 2, is pinned to the ground at O1 and is pinned to the center of gear 3 at A. The center of gear 4 is also pinned to the ground at O1, and gear 5 is pinned to the ground at O5. Gears 3, 4, and 5 are all in rolling contact at point B. Determine the first-order kinematic coefficients of gears 3, 4, and 5. If the angular velocity is ω2 = 15 rad/s cw, use the kinematic coefficients to determine the angular velocities of gears 3, 4, and 5.
