Quoted message said:Victor Papanek said:"Stan the cyclist is keen to stay abreast of latest developments so purchased a hi-tech carbon
fibre rear wheel with 16 radial spokes equally spaced and alternating eight to each side of the
hub. The wheel builder has centred the rim and trued the wheel and then torqued up the spokes to
give a tension of 125kg (sic) per spoke. As Stan lowers his 75kg onto the saddle he wonders what
the tension is in the spokes now."

Do something about your halitosis first. Bait in your breath stinks. It needs abatement.
A previous poster beat you to it, but repetition does enhance recollection (for me, at least).
Quoted message said:Meanwhile, all readers of "the Bicycle Wheel" are disqualified because that is where the answer(s)
to the question are found and the book is most likely the source of the question, this sort of
thing being unknown at the time of its publication.
I doubt if the book is well known amongst the (mechanical) engineering community, who will form the
audience for the original problem. If it isn't in "Kempe's", then it probably doesn't matter...
Quoted message said:
Why did the author confuse the problem by using a REAR wheel as subject? The problem statement is
confusing because rear wheels do not have the same tension on left and right sides.
Who knows? Maybe it is simply a badly posed question, but if the presence of the hub was immaterial,
I suspect the composer would have referred to generic "bike wheels" rather than specifying the rear
wheel. Maybe we are supposed to assume it's a single-speed fixie?
On the other hand, no dimensions are given in the question, so it is impossible to account for the
hub on the basis of the information supplied.
All the same, I'll make sure I snag a copy of the next issue of "The Engineer" for the
published solution
Vic.
