I'd give that film 11 out of ten just because it had David Bowie playing Nikola Tesla. That's rock and roll.

modus anomali An English language Indonesian film. Good action sequences and the suspense is maintained all the way to the twist. F=9 (First time) Exposition dumps in films really get on my nerves because they don't allow you to "discover" anything for yourself. L=4 (Now) Unfortunately, it's...

A Roman delegation did make it to China, where they exchanged various gifts but other than that, the Parthians where pretty good at keeping the two apart. By doing this they made sure that they were the only empire that controlled trade to the west (mega bucks). The Roman school system did...

Real world example: Have you ever stood a straw on it's end (not one with a bendy middle bit)? Did you ever see it bend under its own wait? You just haven't created the right conditions for what you are trying to achieve. In a stable column, any bending that does occur will be so small you'd...

Whether real or just theoretical, a load that doesn't exist cannot be accounted for. Using the critical load method; when it bends (buckles), it's gone. Resistance of bending becomes a moot point. You would have to introduce a horizontal load somewhere along the length of the column for it to...

That's why your column will need to be stiff enough to resist over the effective length. If a column goes into bending when it should be taking a compression load it means something has gone wrong.

That is as good as it gets I'm afraid. Without introducing a lateral load, your column won't be subject to bending. Just buckling under compression.

Now you can start plugging your section properties into that to get the critical load.

Not until critical load is applied (as SteamKing mentioned). Are you familiar with Euler's formula for determining this?

If there are no other forces acting your rod/column then trying to get it to generate bending strain will be difficult (as SteamKing stated). Are getting confused with buckling? Do you have a free body diagram or any attempt at a solution we could look at?

This is one I'm trying to get my head round at the minute too with MathCAD. Work place reports and calculations were always a mixture of a lot of different tools eg. Excel, Word, AutoCAD, hand calcs et al. I've been assured that it is worth persevering with and can see from others work that it...

Just so its clear in my mind: we have a beam spanning 6m with a force of 9N? do you have a sketch of what you are doing? Or perhaps scan in the question page. Just so we're all on the same page lol

I this FAQ on the Edexcel website that I hope can help you out and also this discussion on The Student Room which could be informative. Good luck :)

Wear thick nylon socks and run around with your shoes off lol I think you may have to scale it back a little bit. How about an LED light show?
