A threebar linkage and spring have been designed to ensure that a solid aluminum door panel shuts properly after it has been opened. The door has a width and height of 2m and is 25mm thick as shown in Figure 7.142. Use MATLAB to calculate and plot the x and y components of the force FQ used to open the door. Assume that the door takes 5 s to open and that the spring is in its neutral position when the door is closed.
