If I want to carry a weight along a road in a van, is it better for the load on the engine to have the weight inboard, in a trailer or no difference?
Short back story - I’ve got a 50 year old camper and have just rebuilt the engine. Engine blew because we had too much weight on board (the wife’s fault entirely, told her she takes too much crap!). Now rebuild is done we’re looking at how best to go away, still be ‘comfortable’ and not stress the rebuilt engine as much.
My feeling is the best fix is to take less, but she doesn’t like that option so wondering if having the weight outboard rather than pressing on the wheels would improve the engine load levels?
The engine still has to overcome the same mass and intertia so I would say it doesn't make a jot of difference to the engine. Mass is mass.

Ah but if it's loaded VERY carefully so that it improves the aerodynamics of the whole rig, then those improved aerodynamics might (I say "might" advisedly) more than compensate. This would become more apparent as speed approached supersonic, and should of course be validated beforehand in a wind tunnel. Wheel bearings, tyres, etc would need careful consideration.
I admire and share your optimism and I’m confident that, given the new engine, fuel lines capable of taking higher ethanol fuel without cracking and an improved cooling system, I might be able to push that top speed up to a dizzying 62... (btw, the cooling system is ‘improved’ by putting back on the one that fell off due to rust when we got half way up a hill)As for aerodynamics, short of taking the windscreen and back window out, I’m afraid we’re limited to a situation equivalent to that of a house in a storm.

Not something that I’ve always wanted to know, but on hearing that Scotland are insisting that anyone arriving from Spain self-isolates for 14 days, I assume that if a Glasgow couple have a week in Valencia, on arrival back in Scotland they should follow the isolation rules.
I can’t imagine anyone being that desperate to do this, but what would happen if the couple flew back into say, Manchester, then took a train to Glasgow?
Who (in authority), is going to know that they’ve been in Spain, unless a vindictive neighbour drops a dime to wee Nicky Sturgeon?
Similarly, if a family from Madrid drive to U.K. for a touring holiday in a Winnebago type vehicle, will they be restricted to England and Wales, but have to stay south of Scotland’s border, unless they’re willing to voluntarily isolate?
Even if they fly into glasgow, there's nothing forcing them to self-isolate, unless the authorities are made aware that they're transgressing.I can’t imagine anyone being that desperate to do this, but what would happen if the couple flew back into say, Manchester, then took a train to Glasgow?

It's guidance out there that should be followed if you're responsible. There is nothing in place to actually enforce it.
Why do we have fingerprints, how did they evolve?
It is said that they are to amplify textures but that sounds like a guess by a scientist.
The prints on my right hand have all but disappeared due to work, they are as sensitive to texture as my left hand.

Don't know how they evolved, but their function is to increase the surface area of the skin. It is said that they are to amplify textures but that sounds like a guess by a scientist.

Where you say you have lost your fingertips, the skin is actually thicker and protected by dead cells, like on your foot but less extreme. Underneath the fingerprints are still there.
Just as they increase surface area with the air, or whatever you're holding, they also increase surface area with the lower layers of skin which provide blood and nutrients.
From an evolutionarry POV, I don't know, but would guess that they are a response to the increased wear that these areas suffer requiring more resources and benefitting from more cells concentrated in a smaller area.

What an excellent question. Something I’ve genuinely never thought about at all.It is said that they are to amplify textures but that sounds like a guess by a scientist.

Due to wind why do some trees grow bent, yet some grow straight and perpendicular?
Think its more to do with bending towards the sunlight (ie South facing in Northern hemisphere) rather than wind. Tall straight trees like pines tend to be indigenous to far north climates where the sun is weak and ground water scarce or frozen for long periods.Jonboy_t said:

When you need to move a car that won't start, it is possible to push it. Is this easier than picking it up and carrying it? Thought so!Short back story - I’ve got a 50 year old camper and have just rebuilt the engine.

Does this scenario have any connection with the carry/tow question?

What a stupid question. How else would the police be able to identify criminals?I suppose I thought it was, well, what shall I say - fairly good? You know sort of 7 out of 10. no less, but certainly no more.
I don't like too much enthusiasm for a subject, I find it a little enervating.
EDIT.
I might have given it 6, but certainly not 8.
I've just seen an Mini (original one) on ebay advertised as a Morris Mini rather than an Austin Mini. It's not first time, so not a mistake. Also I've seen MG Midgets advertised as Sprites.
Badge engineering or genuinely different models like Austin Cambridge/Morris Oxford? And how long were they sold alongside the more famous models?

Badge engineering with minor differences (speedo, seats) and both sold for 10 years up to 1969 when they dropped the branding and they just became Minis.Badge engineering or genuinely different models like Austin Cambridge/Morris Oxford? And how long were they sold alongside the more famous models?

The MG Midget Mark 1 and the Austin Healey Sprite Mark 2 were the same as each other except in terms of badging and minor trim. Austin Cambridge and Morris Oxford were certainly not "genuinely different"; they were identical under the skin again only differing in badging and trim (that's assuming you're referring to the Farina models, which also had Riley, Wolseley and MG variants). Minis were originally introduced as the Morris Mini Minor and Austin Se7en (sic); again the same apart from badging. I don't believe either marque was "more famous" at the time, but BMC dropped the Morris and Austin Healey marques, allowing Austin to survive into the Austin-Rover days. Similar happened with the Rootes Group (Hillman, Singer, Sunbeam) and Rolls Royce - Bentley.Badge engineering or genuinely different models like Austin Cambridge/Morris Oxford?
