Q#3: The oscillating fan shown below is to be analyzed as a double rocker. The fan is link 2 , the motor shaft is connected to link 3 , and link 4 is connected from the coupler to the frame. The actual input of the mechanism is the coupler. 1. Write a vector loop equation to solve for the unknown position parameters (i.e. to conduct the position analysis), when \( \theta=120^{\circ}, A D=0.75 \mathrm{in}, A B=D C=3.0 \mathrm{in} \), and \( B C=0.5 \mathrm{in} \). 2. Use the Matlab program template provide on Canvas "Postion_analysis_Chace_solution" or write your own program (using a language of your choice) to solve the same problem and validate your solution
