Question

I am not sure that I am doing this right up to the point that I scanned...is it supposed to be W_B=-5pi rad/sec or...?

Thank you for the help!

PROBLEM 15.49 In the planetary gear system shown, the radius of gears A, B, C, and D is 30 mm and the radius of the outer gear E is 90 mm. Knowing that gear E has an angular velocity of 180 rpm clockwise and that the central gear A has an angular velocity of 240 rpm clockwise, determine (a) the angular velocity of each planetary gear, (b) the angular velocity of the spider connecting the planetary gears.
