Mechatronics v/s mechanical !! :~?

It's depends on what job you want to do in the future. For mechanical is more in the field that related to the overall structure of machine. But mechatronics will plus together the knowledge about electronic. In my opinion, mechatronics got a better market now since it can go into both fields. For chemical engineering, you may get a job in petroleum company etc. While electronic will in the field of chips etc. So, it's depends on in which field you want to be. You should find out more about what job available for the subject because your working career could be 5 times or more longer than your study. GOOD LUCK!
