Huh, cool. Cheers for replying KH.
In that pic the boat looks like it's only being supported along the lowest point of the hull - I'm kinda summing that cannot possibly be the case and there's some sort of lateral support going on somewhere?
They put a row of dozens of those blocks along the keel line, the centre line, under the frames, and because most ships are pretty much flat bottomed they also add them further out to stop it falling over, taller ones, depending on the angle of the boats bum.In that pic the boat looks like it's only being supported along the lowest point of the hull - I'm kinda summing that cannot possibly be the case and there's some sort of lateral support going on somewhere?
I've been in dry docks where they got it wrong, and the blocks didn't go under the frames, so the hull was dented in a few inches in numerous places.

Does the launch angle for maximum distance change according to power, or is there a single angle which will always give the best possible distance for a given projectile, regardless of force?
45 degrees is the angle for maximum range. I used to be able to prove it, long time ago...When a brand runs a campaign of TV adverts for a short amount of time and then changes to another concept (an example which springs to mind is the O2 Centaur character which they ran for what seemed like a few weeks before vanishing, and more recently Go Compare dropping the Go Compare holiday village thing and returning to the opera singer of old), is this because market research has shown the earlier concept to be unsuccessful?
How often do you need to do something before your body starts to make a physiological change? For example I'm rather unfit so if I go to the gym once, does my body go 'oh blimey that wasn't fun. Hope he doesn't do that again!'' Or does it start to make changes based on doing something once, in preparation or as a reaction to what happened?

Twice, technically, but obviously quite a bit longer for anything visible without the aid of a microscope or maybe a blood test. Halmyre said:

Why do radio DJs talk over the intro's to songs - the intro is often the best part or is instrumental (excuse the pun) in building up the song (e.g. Money for Nothing - Dire Straits, One Vision - Queen, Owner of a Lonely Heart - Yes, Poison - Alice Cooper, Come Together - The Beatles, Thunderstruck - AC/DC).

The roundabout appears to be finished and I haven't seen anybody actively working on it for weeks, yet half of the lanes are still coned off.
For example - when coming off the A557 from Frodsham and going right around the roundabout to join the M56 eastbound - there are two lanes on the roundabout for traffic going in this direction. The on-slip of the M56 eastbound is also two lanes - however one of the lanes on the roundabout is coned off which effectively halves the amount of traffic that can get through the junction between traffic light changes and thus leads to queues sitting at the traffic lights.
Does anyone know why the highway agency leaves perfectly useable sections of road coned off well beyond the end of any actual work being performed.

It's to stop you taping the charts on a Sunday afternoon isn't it? [/oldgit]Moonhawk said:

Maybe they are not opening until its had a Stage 3 safety audit, or it might be a case of something not finished (signing, lining, street lighting etc)The roundabout appears to be finished and I haven't seen anybody actively working on it for weeks, yet half of the lanes are still coned off.
