Unformatted text preview: constant rates of d ! /dt = 2 rad/sec and d " /dt = 3 rad/sec , respectively. Find : For the position shown below right with b = 3 ft , = 0 and = 90°, determine the acceleration of point B on the manipulator. HINT : In solving this problem, use an observer that is attached to AD and with a set of coordinate axes also attached to AD. O A B L b x y D O A B 90° x y D...
