Question 3: (10 marks; 3+2+5) The offset crank-slider linkage in the figure has the dimensions and crank angle given below. Use an analytical method, and constant angular velocity of link 2 of W2 = 2# rpm (CW). Find: 3-1) In that moment, where the angles of the links are 02 =14#9 and 03 – 4#º. Determine the angular acceleration of link 3. a3=…… rad/s? 3-2) Calculate the acceleration of pin B. AB=…… mm/s2 3-3) Find the magnitude and direction of acceleration for point A at the same moment. A = ……. mm/s2 A = …… deg. (w.r.t X-axis) a=L2 = 63 mm b=L3= 130 mm offset c= -52 mm А 02
