Incorrect 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?
Gears A and B are fixed, while gears C and D are free to rotate about the shaft S. If the shaft turns about the z axis at a constant rate of w = 5 rad/s, determine the angular acceleration of gear C. 80 mm- 40 mm 80 mm Fl60 mmg Select one: O a. a = 40i rad/s? O b. a = 67i rad/s? O c. a = 32i rad/s? %3! O d. a = 76i rad/s² %3D
