1. Consider a four-bar linkage shown. a) Write a Excel program to calculate angles 03 and 04, the angular velocities w3, 4, the acceleration a3, a4 when the lengths of the links and angle 02 are given. The program should work for both open and crossed linkages. Use your program to find angles 03 and 04, the angular velocities w3, W4, the acceleration a3, a4 for the data in Table 1. The angular velocity of the crank, 02 is 10 rad/sec for all the rows of the table. V In the solution provide the equations you used, the source code of your program and a printout of the output. You can use the algebraic method or use complex numbers to get the equations. 46. 03, 003 link 3 link 4 link 2 02, 002 04,004 Link 1 6 6 19 12 9 Link 2 2 6 12 7 7 link 1 (ground) Link 3 7 7 12 11 11 Link 4 9 9 12 6 6 02 (degrees) 40 60 30 110 100
