Four-bar Mechanism: Given: ri =2.5in.,7.2= 1.0in.. 7.3 = 3.1in., r4= 2.0in., a3 = lin., b3= 1.0in. co2= 5 rad/sec, a2 = 0 rad/sec2 Find: 4 A. Add columns for a3 and a4 to the four-bar spreadsheet used in the previous three homework assignments based on -.Thar template.xls”. Also. include the acceleration components of the coupler point P. A, and An.
B. Plot a3 and a4 as a function of 02. Also. Plot Apo and 4 as a function of 02. Check: a3 (02 = 30°) = 15.8967 rad/s2
