With the popularity of "SUVs'" , how do the manufacturers make sure that they stay (relatively) flat when cornering, what with the higher centre of gravity and the extra weight they carry over a hatchback?
Is it just a case of fitting stiffer springs to reduce roll?
They'll have anti roll bars. As you turn right the weight of the car shifts to the left and presses down on the left side of the anti roll bar. This causes the bar to twist and in doing so lifts the right (inside) wheel, causing the car to lean into the corner. If you see a car with its inside front in the air, it's maxed out its ARBIs it just a case of fitting stiffer springs to reduce roll?
I find things like this brilliant in their simplicity.

If a company changes their logo, do they automatically keep ownership of their old logo, or would they have to apply to keep it as trademark or whatever the appropriate term is?
I saw a lorry this morning which had a logo that was really similar to the old logo of the company I work for, had to do a double take and whilst only slightly different, it just made me wonder.
If they wish to, yes. They retain the trademark ownership in perpetuity (providing the fees are paid).I saw a lorry this morning which had a logo that was really similar to the old logo of the company I work for, had to do a double take and whilst only slightly different, it just made me wonder.
This would only normally apply to the larger companies and brands rather than IDs for smaller businesses.
Most smaller businesses don't tend to trademark their logos so if someone copies it, intentionally or otherwise, it's a case of proving who was first in a court of law...unless the copying company was trying to pass off as the original one in which case, it's a bit more cut and dry and also criminal rather than civil.
On last night's dog walk up on the common, theee was a group of dog owners nattering whilst the pooches ean around and chased each other. Anyway we heard a drone flying. When spotted the direction it was coming from it was clear that it was up at maybe couple of hundred feet, flying at constant height and bearing. It absolutely pissed overhead and disappeared into the distance until we lost sight, though one bod with binocs spotted it a fair way away and apparently still going.
We had a completely uninformed discussion whether this was intentional with a really good pilot, a runaway, or flying along a path set by gps waypoints.
As far the runaway theory was concerned I always thought these things were programmed to return to take off position if they lost connection, but then someone else said even if the drone had that facility you could switch it off.
So any drone bods out there, obviously you won't have a definitive answer but we were just wondering.

Why do people in movies hold torches in that weird way. They hold it raised with their thumb towards the back..
When I hold a torch the obvious way is arm downwards and thumb towards the front.
because framing, holding it near the face makes it easier to shoot a variety of closeups and wider shots.When I hold a torch the obvious way is arm downwards and thumb towards the front.

I’m not sure what you mean by that? Humans still haven’t made contact with aliens.
The furthest we have travelled/sent a probe is not as far as the aliens are at present. Therefore if they are real/on their way they would have set off from a point further than that. Either that or they are sitting in completely the other direction in which case their superior technology makes them better at sneakiness.Never underestimate the sneakiness.

Again, if in search mode and there is undergrowth or basically low down obstacles, holding it higher provides better options for lighting over and beyond in addition to close quarters.
That's without giving any consideration of handling sidearms and illumination, which is usual movie scenario.

Great answer. Hadn't thought of that.One of my movie bug bears is when someone goes to the loos in a bar to throw up, and they grasp the rim of the bowl firmly with both hands and then slide their hands around the bowl too. Nobody, but nobody would do that, especially in some real dive of a bar with horrific loos, but in the movies, they do it every time.
I walked past a dead seagull today which got me thinking: where do all the dead birds go?
I see lots of wild birds every day but rarely see a dead one. For example I live in a fairly rural part of the country, and there are always lots of birds in the garden - but I think I've only ever come across one dead one in 9 years living here.
Are they like elephants and all go to some secret graveyard to die?

Any of those are possible, depending on the model and firmware version of the quad concerned.We had a completely uninformed discussion whether this was intentional with a really good pilot, a runaway, or flying along a path set by gps waypoints.

I believe it is normally cops with maglite-type torches who hold them like that. When I hold a torch the obvious way is arm downwards and thumb towards the front.
And they normally have a gun in their other hand at around shoulder height.
The reason is tactical - if you go into a dark room facing a possible armed suspect, you want the beam and the gun to be pointing in the same direction, with the torch shining down at whatever the gun is pointing at. You also want the torch off to one side, so if the bad guy shoots for the light, he will miss you. if you have a shoulder height gun it is easier to control the torch if it is held in the overhand hammer grip.
Or, it could be framing.

Other animals (scavengers) will eat carrion (dead stuff). It's the circle of life. I see lots of wild birds every day but rarely see a dead one.

Yep - I suspect foxes, rats, crows and badgers hoover up most of them. The crows certainly clean up the left over bits of rabbit carcass off my drive after my cat has eaten his fill of his latest catch. I often see crows scavenging road kill.Cue Elton John...
Maggots, ants and other insects can also make short work of smaller carcasses like sparrows, robins etc
