End A of the 1.8-ft link has a velocity of 4.2 ft sec in the direction shown. At the same instant, end B has a velocity whose magnitude is 5.8 ft/sec as indicated. Find the angular velocity w of the link in two ways. The angular velocity of the link is positive if counterclockwise, negative if clockwise. AQ VA = 4.2 ft/sec 37 Answer: w= i 1.8' B B UB=5.8 ft/sec rad/sec End A of the 1.8-ft link has a velocity of 4.2 ft sec in the direction shown.
