Given: A shaft rotates about a fixed vertical axis at a constant rate of f, as shown below. A straight bar OA, having a length of L, is pinned to point O on the shaft, with O being on the rotation axis of the shaft. At the instant when 80, bar OA is being raised at a rate of 6 from the horizontal plane, with this rate changing at a rate of . A set of ryz coordinate axes is attached to bar OA with its origin at O. A second set of coordinate axes, XYZ, are fixed to ground. At the instant when = 0, the zyz and XYZ axes are aligned with each other.

(Use relative motion analysis): The planetary gear system is used in car transmissions. There is sun gear S, planet gears P and the ring gear R. By locking (fixing/grounding) certain gears you can have different gear ratios and car speeds. = c) If the output shaft is held fixed, i.e. WA 0, and the ring gear is rotated at WR 5 rad/s, find the angular velocity, wp of = the planet gears and ws the sun gear. ως d) What if the planet gears are held fixed, Wp = 0 ?

As shown in the figure below, the wheel rolls on the plane with constant angular velocity w = 1.3 O rad/sec. The plane J on which the wheel rolls is not fixed to the reference frame but instead translates on the reference frame G at constant velocity V = 2.9 ft/sec to the left. Find Vo (the magnitude of the velocity at the point Q). 1 P 1.6 ft J V Figure is from "Engineering Mechanic An Introduction to Dynamics", McGill and King.

pls using just the rules attached in picture i need her all. solving pls veryyy urgent
