In an epicyclic gear train, arm C carries two gears A and B having 36 and 45 teeth respectively. If the arm rotates at 150 r.p.m. in the anticlockwise direction about the centre of the gear A which is fixed, determine the speed of gear B. If the gear A instead of being fixed, makes 300 r.p.m. in the clockwise direction, what will be the speed of gear B ? A Arm C

(Three-Dimensional Motion) The figure below represents a pair of bevel gears A and B. Gear A rotates in ahorizontal plane about a vertical axis at O. Gear B rotates around the shaft OC which in turn rotates about the terminal axis at O. determine the angular accelera tion of gear B when gear A is stationary and member OC has an angular velocity of 10j rad/sec and and angular acceleration of 25j rad/sec2 .

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The disk has a constant angular velocity of 30 rad/s clockwise. D 2.8 in. 10 in. For each of these values of e, determine the corresponding value of the angular velocity of bar BD. Take rA = 2.8 in. and /BD = 10 in. The corresponding value of the angular velocity of bar BD for 6 = 22.9° is The corresponding value of the angular velocity of bar BD for 0 = 192.6° is rad/s (Click to select) rad/s (Click to select)
