na 4R four bar mechanism shown; link lengths: 02A = 80 mm, AB = 300mm, O4B= 120 mm, and 02 04 = 350 mm. The angle 0 = 37. The crank AB rotates uniformly at w2 = 61 rad/s. Location of all the instantaneous centers were given with the dimensions of I12/24 = 131.6 mm, I13/23 = 373 mm, I23124 = 2368 mm and l13134 = 366 mm. Find the angular velocity of the link BC.
