Sacrifice

Toes stop your feet fraying.

Thats not grand prix ...

I was trying to think of all the sacrificial things. Sacrificial anodes on ships, yes. But... how about the face of a wooden mallet? Because the reason it's wood is because steel would be too hard. Because the wood is softer it's more likely to get damaged. Stretching a point? A wooden gramophone needle, which wears out quickly but doesn't damage the shellac? Can anyone think of sacrificial things?

Brake pads; modern brake discs.

Aluminium anode and hot water cylinder/immersion heater.

You could argue that a lot of paint (varnish, etc.) is also sacrificial in terms of function, even if it also adds aesthetic benefits.

I can think of some organisations I'd like to sacrifice employees of, but I don't want to get sued. clue DWP. Brian

Nearly all consumer goods apart from consumable, to include software which incorporate built in obsolescence so as to persuade consumers to purchase new improved or redesigned models or versions every few years thus allowing manufacturers to stay in business servicing a saturated market.

Judging by the number of tyre changes grand prix cars need its surprising the circuits are not made of rubber by now. Brian

On the other hand, some of us take apart Dyson DC59 motorised heads and make them both work properly again and look nice and clean.

Such things should be as easy to take apart as Lego, maybe even Duplo, and not require two different Torx bits. On grounds of hygiene alone, that should be mandated. Let alone avoiding scrapping otherwise perfectly functional machines.

gram needles were often thorns.

Daughters?

Well I never knew that. How did they attach the thorn to the sensing device (diaphragm of mechanical horn, moving iron in coil, or piezo crystal) sufficiently firmly that no frequencies were attenuated by the flexibility of the thorn and of the thorn-to-sensor joint and yet which allowed the thorn to be replaced quickly and easily whenever it wore down?

Interesting that "modern" (well, before LPs were supplanted by CDs etc) was the exact opposite philosophy: stylus made of diamond which is extremely hard, and which could theoretically damage the vinyl record.

Guinea pigs, apprentacies and students :-)

And accrding to Brian Cox last night perhaps even the universe.

As this threads development shows, there's a distinction to be made between "consumables" and "sacrificials" ?

[Bill Wright]

Yes, a lot of people has misunderstood. 'Sacrificial' means that the item is lost, damaged, eroded, etc IN ORDER TO PREVENT DAMAGE TO SOMETHING ELSE.

On a drag race track most of it seems to be left on the track. Walk the track at the end of a meeting with certain types of rubber or plastic soles on your shoes and you will stick to the track quite firmly!
