In the differential gear with internal gearing 1st gear crank OA rotate independently from the angular velocities ω1 = 2 rad / s and ωOA = 4 rad / sec. Determine the angular speed of the gear 2, if the radius r1 = 30 cm and a crank OA length is 20 cm.

Right after the payment you will receive a link to a zip archive with the solution of the problem 9.2.11 (Chapter 2 - Kinematics, theme - 9.2: The angular velocity of a plane figure) in theoretical mechanics from the collection of short tasks Kep OE, JA Viba, OP Grapis, JA Svetinysh et al. Publishing Moscow / Graduate School / 1989, 2009, 2012. Task completed in word format (handwritten or typed solution in Word) or in manuscript form in the format gif, packed to the archive zip (open on any PC) .After checking the solutions would be very grateful if you leave a positive review.
