    And can you not hang out with myth? He did tp for a while.. Then joined the cool kids..;)

    Yup, for first year myself and a few others were called 'TP Refugees' by some of the lecturers.

    If you're thinking of organising a meet-up just do a main tcd boards beers and get engineers to go, and then just alienate everyone else who goes to it.

    There were 3 of us who moved from TP to Engineering, and I know someone else who moved from Maths to Engineering a few months before.

    Hi, can anyone help? Im tring to select the correct motor. The motor simply has to pull a weight of 2kg. How would I calculate the required torque? The speed isint important but It probally comes into calulations somewhere? Does it relate to the torque?
    Sorry I knew I sould have been more specific but in my defense I am new to this! The motor actaully needs to lift this weight if u get me. Imagine a standard dc motor is on a bench and needs to pull a 2kg weight up from the ground. How do I calculate the torque required. I then need to select the correct motor. But I do need to state my calcuations used! Any help would be great! Thanks!

    T=F*D

    where:
    T = torque
    F = force = mg = 19.62
    D = distance

    thanks jim but what distance do I use? Is it the radius of the motor shaft? Just say I am using some sort of leadscrew mechanism that is connected to the shaft. Does that change the distance that i will use?

    Ah go on. I'll be the guy wearing the sudo make me a sandwich t-shirt.

    Although apparently someone / a couple of guys in CS have the same t-shirt, so if they don't look super sexy then they're probably not me.

    Sweet, would you mind writing up my Physics lab too?

    Real question - When does Mechanics stop being stuff I've done in Applied Maths and turn into something worth taking out my earphones for?

    Conservation of momentum and collisions.

    Stuff straight out of Ollie's book.

    Man you should have sat in on that guy J.K. Vij's lecture, some guy wrote "Bring Back Igor" on the blackboard and honestly I couldn't agree more after that lecture. Heh or graphics. Dr Ghosh (or Prof Ghosh I can't remember) really lost it today. Told us we were the most insignificant part of her job and that graphics isn't even her area (never would've guesed...). Shouldn't they give us an architect lecturer or something for that? And have tutorials instead of lectures? Cause the whole idea of a graphics lecture just doesn't seem to work. I'd say it'd be well better if we had the tools in front of us to actually do the feckin drawings instead of her trying to do everything with a piece of chalk. I've to go in now tomorrow and draw a buncha crap in isometric and I've only the mildest idea of how. Ah well at least the tutorials are not graded or anything... oh wait.

    Its Prof Gosh.

    Graphics isnt a hard subject. Its very logical. When its thought in school its done the same way except you have more hands on with the drawings.
