Question
I drew perpendiculars of the velocity vectors forvA and vB which intersected at, say, D. AD equals 10/cos(35) = 11.547 inches. BD = 11.547sin(30) =5.7735. vA should equal r or (AD) or(11.547/12) = 1.24708 rad/s. But this is not the answerin the book. Rod AB is attached to a collar at A and is fitted with a smallwheel at B which rolls on a circular surface. Knowing thatwhen = 60o the velocity of the collar is 1.2ft/s downward, determine, at that instant, (a) that angularvelocity of rod AB, (b) the velocity of point B. My strategy was to draw perpendiculars to the two velocityvectors and find the intersection, say, D. I figured that theangular velocity () of rod AB =vA/|AB|. But my answer doesn't match the answer inthe book. What is the correct way to diagram this problem andcalculate the angular velocity?
