Consider the case where the ring gear R is held fixed, wx = 0, and the sun gear S is rotating at - 5 rad/s. Determine the angular velocity of each of the planet gears P and shaft A. معلم هذا السؤال A 40 mm mm ایران اخبار

Answer 1

Datu given WR - Ws = 5 rad Is 2x80 ds - 160mm diameted of sun gear 2x40 = 80 mm of diameter planet year, de a de dr = dst dia of Ring gear Balomm Su 160 + 2x 80 table. а.
