Realise this doesn't deal with the friction issue but does this help?
That's how I understand it, transferring more of the weight to the pulley and it's support.It's how I understand cranes work: one rope (at top of image) connected to one winch motor of a fixed capacity, but the lift capacity can be increased by rigging the hook on more 'falls' of rope. More load is transferred to the jib head as number of ropes increases.

A bit blowy yesterday, so wind turbines.
I expect they come in different specifications, but are they able to still be used in such windy conditions without having to turn the blades out of the wind? And, how do they cope with the gusts?
The turbines adjust themselves to maintain a constant power output over a range of wind speeds, in large turbines usually by adjusting the blade angle.I expect they come in different specifications, but are they able to still be used in such windy conditions without having to turn the blades out of the wind? And, how do they cope with the gusts?
It gets to a point eventually when the wind gets too strong and the force on the rotor increases to the extent that it risks being damaged. At that point a braking mechanism is deployed to bring the whole thing to a stop.
If the braking mechanism fails it can be quite impressive. https://youtu.be/ECqpbqbT3UA

Windy weather. If I think back to when I started driving, 105E Anglia, Mk1 & Mk2 Cortina, Mk 1 Escort, Mini, any really windy weather from cross winds and you got blown all over the place.
Modern cars not so much. Why?
Manufacturers are more savvy about aerodynamics, true, but would have thought that something designed to have least resistance in a straight line, which is 99.99% of the time, then wouldn't they be more affected by large crosswind gusts?
OK, cars are also a lot heavier, that would improve things, but they are also a lot larger so more area in side profile so that works the other way and increases susceptibility.
wider tyres, with better grip, will contribute a lot. Modern cars not so much. Why?

The suspension in the S-Class (and I'm sure in other things too) detects cross-winds and compensates accordingly.
After t being mentioned in the "films I watched thread" I re-watched some of the Olympic 2012 Opening ceremony.
Obviously as a hardened man, I can only assume that someone is chopping onions near me every time those giant rings meet in the middle. Even four years on, having seen it loads of times!

So my question is this:
"Why when you get emotional, (happy or sad) does your nose run?"

Your tears drain through the tear ducts into your nasal cavity.Obviously as a hardened man, I can only assume that someone is chopping onions near me every time those giant rings meet in the middle. Even four years on, having seen it loads of times!

Frequently they will be shut down with feathered blades in order to prevent damage from excessively high wind speeds.I expect they come in different specifications, but are they able to still be used in such windy conditions without having to turn the blades out of the wind?

Regarding gusts - have you seen a wind turbine up close? They are f'ing massive! and as such gusts are "soaked up" due to the intrinsic mass of the things.

Ahhh. 
2 Further questions
1) So why don't my tears come down my face. But go internal? I have cried in the past so presumably there's nothing wrong.
2) Why do we cry anyway if we're emotional? I can understand eyes watering if you get something in them as it's trying to flush the dirt out. Seems an odd reaction when you think about it

I have loads of internet accounts and loads of passwords like anyone else I suppose ... but what if you die ... how do family/executors access websites, online banking etc. ?
All my online details are in Keepass. Password to the Keepass file is in with my personal paperwork bits in the loft. Wife has instructions to post as me from beyond the grave on Facebook, but I don't think she has the same sick sense of humour that I do
