(music) Hi , I'm Drew Murry and I teach here at Kettering
Labs. The classes I teach are in mechanical engineering. (sound in classroom) You have
to refer to the kinematic sketch in this case. Looking at this device is no good because
it stops moving here. "It just really helps for everyone, to have different props and
visual things to see. " It's ability to move...as this link rocks out and stops, and comes back.
Yeah, that's one of the things regularly cited on my evaluations. "Generating a force out.
Force out is finite." Is the fact , I have a cart full of things like that.
(music...the name game song) He calls on every individual by name, every
class, so you know you're going to get called on, and it makes us pay attention. "There's
a definition of mechanical advantage that we adopt, that you get when we took statics.
Scott ? The calling on every person in every class is a part of the philosophy. "Now last
time we took the time, Kevin." I actually learn the names and go around the room. I
don't want them to get the answers wrong, but when they do get the answers wrong, I
actually think we learn something. (laughs) "You're close. Mike can you get it right?
He's down the right road. " I really enjoy how personable he is. He knows
every student by name, and doesn't hesitate to call us out on it, whether or not we're
paying attention, which definitely helps us to stay more engaged in the class.
I try to have a sense of fun in the classroom. We're not there to goof around, and it's not
play, but I don't think things being light hearted is a problem at all. "Yeah, the pipe's
great. It makes it exciting. Dr. Murray is one of the most fun professors I've had at
UD." The Ted device we'll call it. You know you
can laugh for a minute and you can get right back on track, and that makes it ok.
(music) I think it helps keep attention in the right
place. To not have those laptops open in the classroom. I'm a human being too. I know if
I have a laptop in front of me and I drift for thirty seconds, I'm not paying attention
to what's going on in front anymore. And the students , I think, actually like having those
paper packets in front of them, that they're filling in the blanks that I left out of them.
When we do the MATLAB section and we have the laptops open, I immediately know who's
doing other things, because nobody smiles at MATLAB. But you do smile at Facebook, and
Twitter and those things (laughing) I think the smartphone thing is pretty cool,
and I tried to talk to some students who seem to have an interest in it, about developing
apps that would actually be helpful to have in class. I don't know if it's something I
can make work as a professor, you know, without some kind of development studio behind me.
Dave Myszka, my colleague in mechanical engineering , and I run the Design in innovative machines
lab, or the DIM lab. We wanted to do something that was mechanical engineering oriented.
(music) Mechincal advantage is the amplication of force using a mechanical device. A lever
can be balanced on a fulcrum. If we move a fulcrum to one side, it takes less weight
on the long side to move the short . This car weighs considerably more than I weigh.
But with a long enough lever, we can lift the car, using only my body weight. We do
a lot of projects. The one I think we're most excited about, and spending the most time
on right now, is the concept of variable extrusion dyes for polymers. (music)
I grew up in Connectuicut. Did my undergrad at Rose Hulman in Terre Haute, Indiana. Went
to the University of California at Irvine for my masters and PHD. Did a post doctorate
in the south of France, and then came here (to UD) after that, in 1997.
My wife's name is Lynn, She's in the culinary arts program at Sinclair, learning to be a
chef. My oldest son Quinn is 13, in the 7th grade. My youngest son Julian is ten, and
in the 4th grade. The boys are really into this game called Pathfinder , which is the
modern version of Dungeons and Dragons. Trying to be superdad, I'll sit with them
for a few hours on the weekend, and pretend I'm either an elf wizard or a half orc monk.
I was just talking to somebody the other day, and they said we should clone Dr. Murray a
dozen times over and make him teach every class, because he 's the best professor here
at UD. (music..)
