In this months MEW magazine (Model Engineers Workshop) there is a comment by
the editor to a readers letter.

'On the general subject of strength of bolts, I like to keep in mind the
comment made by the late Colin Chapman "You can hang a double decker bus
from a 1/4" bolt" <snip>

I am sure Colin said many things, this is one I have not heard before, has
anyone else come across it?

I've not heard that quoted before.
What do you thing the chances are or it being true?
I wonder what a double decker bus weighs?
I'd guess at 14560 kg
Now over to you Mr Phillips would a 1/4" suffice?


Paul (no idea on this one) Adamson.

According to the EU directive, the tensile yield strength of a 6mm (1/4" inold money) bolt must be:

Yield strength Rp0, 2 min 640 MPa.

So does that answer your question?

Pete.

Good thinking Ian, but too technical for me. I am still thinking about where
the UK bus industry would be today if Lotus had made buses.

BTW, where is everybody? us CLOGs seem to have taken over this group
tonight, well in a small way.

Paul,

1/4" dia bolt approximate cross section area 1/20 square inch, estimated tensile strength of cheap 1960 British steel = 30 tons/square inch, max bus weight = 30 x 1/20 = 1.5 tons

Maybe the rest of the LotusElan.net are out driving along winding
mountain roads.
Leaving a trail of Porches and BWM's in their oily tracks.

Bob Metz is parked at a drive through trying to explain why his car has
no "Cup" holders. Super size or otherwise.
Rob LaMoreaux is trying to measure the luggage capacity of his Elan -v-
his Corvette
65 Lotus was hurt in a bizarre "Gas tank" welding experiment
ardee_slby is trapped by defective door stays
Brian Goodison is still perplexed by his gearbox
Briggs Pletcher is looking for a windshield
***@***.*** in Africa or someplace.
e s is playing at a re-wire.
Edwards Ray, is gluing a model Elan together
elanspring71 is struggling with his bad back.
Ian Phillips is attempting to measure the tensile strength of 1960's
1/4" bolts. (We want a graph)
Brian Gush is trying to get an S4 bonnet (hood) to fit an S2..........
eFFing Ian is gazing a grazing sheep.
Trevor can't get his starter to start.
Gareth is busy changing his wheels.
Scott potter's looking for a grommet
Sean murray's got 5 speeds and a squeak
William "kip" king can't get his dipping stick to seal
&
<Drum roll>
At the end of the alphabetical list.....
Zuckerman tells us that "Land Rover is owned by Ford."


Get out more Zuckerman!

In accordance with the British Standards which have now been adopted
into the BS-EN fraternity (ie nicked by Brusseles) the steel is in 3
grades, that were in the 60's, grade 43, 50 and 55 now know in
accordance with europe as S275, S355 and S460 and to complicate things
even further there are two sub grades ie 4.6 and 8.8.....why they
changed it us Brits still don?t know....ah well.....
Anyway.....generally the shear capacity of a 6mm bolt is 66.25kN
(6.52ton)...bearing capacity 69kN(6.79ton)...tensile capacity 39.75kN
(3.91ton)
10N = 1kg.....1kN = 100kg therefore shear is 6625kg bearing is 6900kg
tensile is 3975kg.....
It now just depends on the size and weight of your bus......
Are we going into the european truck racing scene????
Cheers
G
