Question

Transcribed Image Text:5/64 The rotation of the gear is controlled by the horizontal
motion of end A of the rack AB. If the piston rod has a con-
stant velocity * = 300 mm/s during a short interval of mo-
tion, determine the angular velocity wo of the gear and the
angular velocity @AB of AB at the instant when x =
800 mm.

For the position 0 = 34º, determine the angular velocity WAB (positive if counterclockwise, negative if clockwise) of AB by the method of this article. (Suggestion: Choose a point D on AB coincident with C as a reference point whose direction of velocity is known.) Answer: WAB -20" 13.92 B rad/secarrow_forwardIncorrect The Scotch-yoke mechanism converts rotational motion of the disk to oscillatory translation of the shaft. Using the values e = 30°, w = 5.4 rad/s, a = 2.1rad/s?,r = 230 mm, d = 610 mm, and ß = 16°, determine the velocity and acceleration of point P of the shaft. The velocity and accelerations are positive if to the right, negative if to the left. Answers: Vp = -0,563 m/s ap = i -6.195 m/s?arrow_forward
