Four cam spring
Got most of the studying down, have those springy springs down pat and I am pretty sure I could design a cam. However, the Four-bar Linkage systems are a completely different story. I just can't seem to wrap my mind around the mechanics or the kinematics of this system. I'll go through a problem, think I am on the right track and then get completely lost. If only there was a way to sneak this into the exam. Oh well, I will give it another try tomorrow before the midterm. Hopefully something will click and the physics of this system will no longer elude me.
