A four-bar linkage is shown in the figure (the ground "link" OC is considered the fourth bar). If the angular velocity and angularacceleration of drive link OA are 6.1 rad/s and 6.6 rad/s² respectively, both counterclockwise, determine the angular accelerations ofbars AB and BC for the instant represented. The angular accelerations are positive if counterclockwise, negative if clockwise.14°285 mmA95 mm245mmwo/69°土Answers:αAB= i2.356rad/s²αBC=i11.327rad/s²

The angular accelerations of bar AB (α_AB) and bar BC (α_BC) can be found using the loop-closure…
