Say a car was involved in a fatal accident and ended up properly mangled, what would happen to it other than be crushed? What would happen after the police retrieve it etc, and would it ever be sold on? E.g copart
I work opposite a recovery firm who deal with the south eastern section of the M25, they often have the managled remains of serious and fatal incidents and there's often a police forensics van on site. The more serious ones can be there for months and are crushed once the coroners report and any insurance liabilities are handled.
Ah, do they ever get sold however?
I suppose it depends. if the driver just had a heart attack and died at the wheel with minor damage to the car I'm sure it would be Cat C/D depending on the damage. However with modern safety I doubt any car where the driver or passengers have died would be in a condition where it could be re-sold.
Would it become a Cat B? What is that anyway?

I don't know for sure but I do know that when my dad had his 205 he needed a replacement parcel shelf and that he acquired one from a car that someone had died in from a scrappies where he was carrying out an investigation into a different fatal. From that I take it they get broken up for parts and then scrapped.

That said he told me about an accident where a woman left the road and went through a hedge. Very light damage to the front of the car and she died. They couldn't figure out why since she shouldn't have had so much as a scratch on her. I doubt they scrapped her car seeing as it was perfectly good just needed a new bumper and front end resprayed.

When a washing machine finishes a cycle why does it take 2-3 minutes for the door to unlock?
It's a very good question and i've never heard or read a good answer apart from 'Safety reasons' and 'just in case something goes wrong'.
Which aren't very satisfying. When the machine ends its cycle you should be able to open the door, it's already stopped spinning and water was drained away ages ago.
Older washing machines used an air pressure system to lock the door. The pressure was created when the water in the drum blocked a small tube and increased the air pressure in it. You can often see a small plastic pipe if you take the lid off and look down towards the lock. The delay in unlocking was the lime it took for the pressure to release and unlock the door. Modern machines use an electronic solenoid and unlock whenever the computer tells them to.

Truth is they all get sold to someone.

When it's written off, it's assigned a category:

But even burnt out shells, or mangled wrecks are sold, crushed and melted to make new materials, I hadn't thought about it till now, but it'd be pretty grim to be the guy loading up the blood soaked wreck of a family wagon into the crusher, obviously they'll remove the bodies, but there's still going to be a trace isn't there. Horrible.

I don't think they can bury them or anything.

What uses more leg power - walking up stairs or pedaling a push bike?

Stairs - each leg lifts your entire body weight.

Bike - riders are not exactly lifted from their seats by pushing down on the pedals.

I appreciate there are many variables, but in general how would the two exercises compare?

As you say, with the number variables I don't think there is an answer. If you try to start your bike in too high a gear you certainly will lift yourself out of the seat. You can also accelerate as hard as your legs will allow on a bike, if you try the same on the stairs you will jump up them two or three at a time.

Cycling is more efficient than simply walking on the flat ( source) - so it would certainly use more energy climbing than cycling (and thus more 'leg power', almost regardless of how you define that).

When you're listening to Test Match Special, clearly there is a delay on transmission. You can see typed commentary on cricinfo before the TMS commentary is broadcast.

How long is the delay roughly and why, is it simply in case Boycott rips out a fookin' rubbish when someone plays a particularly bad shot and gets out.

Most live broadcasts on both radio and TV have a built in delay for the "Boycott" factor (or any other of the type). I always thought it was 5-10 seconds. I also notice there is a lag in transmission type eg Satellite takes longer than ground based because of transmission distances and strangely HD channels seem to be dealyed vs the same channel in non-HD on the same equipment, certainly does on our Virgin fibre anyway.

Yes, but on the other hand with cycling you cover more distance.. so it should not be based on distance covered, but time spent.

What would get you fitter, half an hour walking up and down the stairs of a 20 story apartment block or half an hour cycling?

Depends where you ride/how hard you go, I can go out locally and spend 30 mins up hills so step you'll be broken after 30 mins of repeats.

Actually called the Profanity Delay, normally 7 seconds but hardly ever gets used as such as it's very difficult to bleep a rude word in a live transmission without having someone hovering over a big red button. You have to find the profanity on the sound wave, highlight it and remove it or reverse it...while the sound file is moving...all in seven seconds.

It's used more these days to even out the variation in natural delays through different broadcast means (analogue, DAB, online, satellite, etc) so everything is set to the slowest.

I do a bit of radio and the station has two studios, 14 miles apart. Studio B is connected by fibre broadband to studio A where the signal goes to an FM transmitter. Through my headphones in studio B, I hear what comes out of the desk but switch a switch and I hear what someone would hear on FM or Online. FM is 1 second behind me and online is 5 seconds. I have in the past had a game I play live on air where guests are asked to read some local news article but using the FM input into their headphones and see how far they get into before it affect them. It is the funniest thing as they slow down their speech to wait for the signal to catch up but they just......end.........up................speaking...............really..................slowly.

The only one I know it does get used regularly on is Soccer AM on Sky. I guess because its a morning program which plenty of kids watching but generally an adult theme to the guests and interviews. They tend to just blank the sound for a few seconds. Must have an employee with exactly that JD angel

To make sure all the water has drained out. Otherwise you'll get a wet floor. I expect it doesn't take that long to drain, but someone numpty would no doubt be claiming for compo on that one occation it takes longer than say 30 seconds and they flood the kitchen/utility whatever
Its a pity that washers aren't designed so that the door unlocks immeadiatley after the spin cycle only,when there is no water to spill out

Mine does - an old Miele Novotronic W454 Edit - it's an 828. I always wanted a big-block washing machine though.
As soon as it stops the spin, you can pop the door open.
Last one (AEG I think) took a good 2 minutes before you heard that "click" and could open it.

I don't think they have a delay on the BBC News Channel. Earlier on they had a reporter on location and about 2 mins into a piece she loudly and disgustingly cleared her throat and muttered 'I think I'll start that again'. I guess she thought this piece wasn't going out live.

What is the strongest spring material in the world? As in force/mm of deflection?/thickness.

How big would a steel coil (like from your suspension) spring need to be to launch 100kgs past escape velocity?
