For the problem related to Fundamental.4, a sketch of the considered system showing and naming (or numbering) every part of the system considered, the respective velocity and acceleration of each, and the frame of reference considered is mandatory. Its absence will automatically make the problem false. Gear A on the drive shaft of the outboard motor has a radius rÃ=8 in. and the meshed pinion gear B on the propeller shaft has a radius r=50 in. The point P is located on the propeller's tip at a distance 10 in. from the neutral axis of the propeller's shaft. B At the beginning of the propulsion, the drive shaft rotates with an angular acceleration a = what must be the value of A to have, while starting from rest, vp=28 in.s¹ in 8 seconds ? A. t2.3 rad.s2 where t is in seconds.

5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity W and angular acceleration a (both counterclockwise). 6) if W = 4.4 rad/s and a = 7.7 rad/s2, length I = 1.7 m, and angle 0= 27°, what is the angular acceleration of link AB in rad/s2? Please pay attention: the numbers may change since they are randomized. Negative must be included if it is clockwise. Your answer must include 2 places after the decimal point. 0.5 m A 0, a B Your Answer: Answer

A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the angular velocity and angular A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the angular velocity and angular acceleration of drive link OA are 6.1 rad/s and 6.6 ras/s^2 respectively, both counterclockwise, determine the angular accelerations of bars AB and BC for the instant represented. The angular accelerations are positive if counterclockwise, negative if clockwise. The answers are not: aAB= 2.356 and aBC = 11.327 or 390.82 and 465.7
