    Hi All,

    I'm hoping someone can help me with force on a beam.

    (1) What is the concentration of loads in the centre of a beam called?

    (2) What is the concentration of loads at the end of a beam called?

    All help appreciated. I think is point load but I'm not sure and I haven't got a clue what no.2 is.

    Thanks in advance

    Hi OP

    This sounds a bit like you're asking us to do your homework?!

    Can you give us some context as to why you need to know.

    No, now I haven't done homework for a few years, shame I wish I had youth on my side.

    I was thinking of studying Civil Engineering and I'm working through a physics book I was given and those are two of the questions from it. I've been through the chapter a few times and I'm confusing myself between bending moments, shear, torsion, point loads, compression and tension. I was just looking for a bit of help is all.

    Concentrated force - point load

    Force at end - support reaction

    Bending Moment = force x distance

    Enjoy!

    The two of you seem to be in the know........where's a good place to start from scratch. The book I got is a bit advanced for me. Do you think a JC science book would be the best place to start?

    Learn about forces and moments from junior cert physics ...lever arms and that kind of thing. That's the foundation (pun intended) that all the rest is based on.

    A "bending moment" is an awkward thing to get your head around so start with learning about forces and reactions and work up from there in my opinion.

    Apologies if I've over simplified - I'm not sure what level you are at.

    Structural mechanics book.
    That's what we used in civil 1st year.

    I'll get the name tomorrow as I still have it on my desk.
    Should get you to grips with BMD, SFD etc

    This fella might be a good place to start.
