Colins quotes

PostPost by: "Ian Phillips" » Thu Feb 10, 2005 9:35 pm

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?

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?

How about E=MC2 :-)

Don't forget that if it was a Lotus bus it would be very light !!!!!!

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

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

Does this include the passengers, driver and conductor? Ding, ding move
along please, there's plenty of room on top.
