Merry *ff*ng Christmas

3) The wheels on the bike go round and round, round and round, round and round. The wheels on the bike go round and round, all day long.

I hope this is clear.

4) See 3.

Crikey - a 14st 4lbs person being referred to as a fatty!

That was my 'skinny' weight when I had a 31" waist and a six pack!!

1. 1 mile

2. 100 psi

3. No, the world revolves around me

4. As fast as possible, although it makes very little difference - https://www.sciencefocus.com/planet-earth/do-you-get-wetter-if-you-run-o...

1) Let's see - after 1 minute, #9 has cycled 1/3 mile and #10 has cycled 0 miles. But by the time #10 has cycled 1/3 mile, #9 has also cycled a bit further. So no matter how many times #10 cycles the same distance, #9 is always a bit further ahead. Therefore it is impossible for #10 to ever catch #9.

2) With a bit of finite element analysis, we can determine that the rider and bike are being supported merely by the pressure in the tyres and the rigidity of the Gatorskins. As the casing is assumed to be perfectly rigid, this means that the air pressure is not supporting any weight at all. Thus, we can prove that the tyres are merely subject to social pressure to perform well as tyres.

3) By examining the contact point between the road and the tyre, it's clear that the tyre is static at that point (unless you're performing some wicked skids) and so obviously, the entire wheel must be static too as it is a rigid structure.

4) I'll take option b) please. Imagine if you will, the trajectory of a raindrop falling vertically onto my head. If I then move forwards, the raindrop will surely fall behind me as long as I am moving quickly enough for the time taken for the raindrop to fall is longer than the depth of my head. This means that I can remain completely dry unless the clouds are low - this also explains why misty rain is a lot wetter than ordinary rain as the clouds are lower.

*Supplementary question: what's the smallest pet in the world?

I keep a small proton as a pet - it helps me stay positive.

For bonus points - see if you can connect the dots in this picture:

1. He doesn't. TTs are so phenomenally dangerous that the whole thing is called off due to it causing a massive accident before he has the opportunity.

2. Trick question. He's a fatty, so he would be riding large tyres at lower pressures.

3. Only so long as there isn't a Very Important Driver who requires me to pull over out of their way.

4. c) I ride slowly and cautiously and pull over and stop every time I encounter a Very Important Driver, cheerfully accepting the drenching as they speed through the puddles with a courteous wave in response.

[I may have collaborated with another regular poster on my answers - I hope that's OK?]

1) You didn't mention that no 10 had a diminutive friend in the race so we can't tell*

2) If latex tubes, atmospheric pressure only. If tubeless, we won't know until next week as they still haven't seated. If butyl, it's winter so we need to know where the thorns have been inserted.

3) No, it's the wheels on the bus that do that. Were you not concentrating at nursery? Don't they teach them anything nowadays?

4) Neither. You call nic mason to drive you home and you get there before the third drop has fallen, as there is no need to adjust speed or course for mini roundabouts or speed bumps.

Have I won?
