Long pre-computers, finite elements, etc, there was a method for stress analysis which used polarised light and perspex models.

I remember seeing a photo of a crane hook under load.

Google images suggests it's still a useful method!

We use a polariscope in the lab when looking at glass articles.

Everyone who's done A-level physics in the last 50 years has seen that photo!

It was the company my dad worked for that developed it. The image was in the company's staff magazine.

And, yes, over 50 years ago :(

Edit They made the centrifuges that 'graded grains for finer flour' too :)

I went to Bath Uni for a look around the (applied) physics dept many moons ago and they had a quite impressive scale model bridge made of perspex for stress analysis purposes.

It is if you've just crashed through a glass ceiling!

If you want waterproof and warm clothing, buy what mountaineers buy and wear.

Not much crash protection, but there is always a trade off with everything.

Fiel injection has to be my favourite improvement over the last 30 years.

Tyres, brakes, frames and suspension improvements were just evolution.

Not many inventions.

Slipper clutch makes track use better. Not much difference on road.

ABS. Good for road. Not track.

Quick shifter. Gimmick. Right up there with ashtrays.

Wings. Track yeah. Road. See above.

TC good idea. Not to be relied on. See how many high-sides in MotoGP.

I forgot body armour. We raced in 80s with bugger all knee and elbow protection.
I feel a bit safer in my Dainese leathers :D

Nobody’s mentioned assless chaps.
