Freecycle: Broken Fort Track 7005

its quite simple really ...

He used bernoulli to fix that frame? Impressive.

is "Jim'll fix it" still around, I'm thinking he might have to work at this one,

hmm though modern day it may be worth contacting "pimp my ride", they make rusty old crap heaps look good again, it might even take the smile off the big fella's face....

That'll polish out, I've definitely seen worse ;)

Good as new :)

I'm confused.

What's going on in that photo Brucy?

Zombie bike.

Epoxied?

GRP, Glass reinforced plastic=)

I am just now studying the effects of GFRP or CFRP strengthening of beams, columns and slabs. As the fort is neither a beam, nor a column, nor slab, and in addition is not made of concrete or steel, and is most probably subject to impulsive or harmonic loadings rather than statics, I will skip my original idea of a bond strength analysis and move straight to my gut response:

"brittle failure ahoy" :-)

(I'm sure you know that though Brucy. Looks like fun. Have you steepened the head angle compared to the original geometry?)

i don't know if i would be comfortable riding that. looks like it could go at any minute. a marvelous job none the less.

I was confused, now i'm intrigued...

I might go to easts next week, drop by with the bike if you can I'm dying to have a look.

Grp was designed to replace wood on planes harmonics i think not:) anyways what you studying?

Fort my arse, it was an Apollo !

Its an apollo now:)

:d

Hey Brucy-

I meant harmonics as in sinusoidal vibration (comes from rotating components, e.g. driveshafts in engines - so maybe bike wheels?) but i think impact loads would be dominant. Or perhaps fatigue. Anyway I was just rambling.

I'm studying structural engineering and one of my research interests is carbon/ glass reinforced polymer bonding. It's used for strengthening structures which are already built. I'm interested in the stresses in the adhesive layer betwen plates bonded together- this is not yet well understood and it's a fair bit simpler than repairing a bicycle frame!

/nerd rant

Jump it down a 10 set!

Backwards! While on fire!

Brucy can you stil fix my teeny weeny crack in a steel frame that for the moment I'm riding (pre-catastrophic-failure) with the aid of a Jubilee clip? Pretty please?
