The flywheel turns clockwise with a constant speed of 580 rev/min, and the connecting rod AB slides through the pivoted collar at C. For the position θ = 48°, determine the angular velocity ωAB (positive if counterclockwise, negative if clockwise) of AB by using the relative-velocity relations. (Suggestion: Choose a point D on AB coincident with C as a reference point whose direction of velocity is known.)

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
