Tom's dad has some Examination Papers from 1960. Anybody care to try this one? Can anybody under 50 answer this one? The paper is full of them.
"A rectangular tank is 4ft 6 ins long and 3 ft 4 ins wide and contains water. A solid weighing 2 cwt 3qtr 12 lb is totally immersed in the water. Find how many inches the level of the water in the tank rises given that 1 cu ft of the solid weiighs 256 lb."
The paper is full of stuff like this and had to be completed in an hour and a half.
Nothing to do with swinging. Sorry. But how many people can do this sort of thing nowadays?

if anyone whats to know the the answer for gods sake dont ask me for it 
Mod
Well if it helps kickstart an answer, the weight of the object in pounds is 320lbs, which is also exactly cubic feet.
I'll let someone else complete the next stage! :shock:

Since the area of the tank is 2,160 square inches and the volume of the solid is 2,160 cubic inches, the water rises one inch.
I've been puzzeling over this one for about 20 minutes now. Reminds me of my maths classes back home. My maths teacher in standard 7 (form?) was my favourite teacher. Bloody wish I could remember her name. But it's only her name I forget. I'll remember her forever.
I fell asleep in the first math class I ever had with her. That's when she gave me the two choices I could make that would map the future of my life. I could pay attention and actually learn something. Or I could take my trashy Daniel Steel books and go read in the sun or under the tree.
Man, you should have seen my tan.

A guy with a PhD initially said this was a trick question. But confronted by the paper itself - aimed at 15 year olds came up with the one inch answer.
Like another from the same paper?
A party of men agree to pay equally for the use of a boat and each pays one and threepence (that's 15 pence). If there had been two moe men in the party each would have paid tenpence (I don't know what that is now) Calculate the number of men in the party and the cost of the hire of the boat.

Leaves me out cos I am over 50 but how deep is the tank 
: :?: L x B x D = :?: :?: :?:
Fred
Doesn't matter how deep the tank is: 2,160 cubic inches (i.e. cubic feet as Mal says) of water is displaced. The area of the displaced water is the same as the dimensions of the tank as given, i.e. 54 X 40 = 2,160 square inches, therefore the depth of the displaced water is volume divided by area = 2,160/2,160 = 1 inch

That was too fast. Is it right?
Try one last question. I think this one is pretty impossible.
A solid cylinder floats upright in water with 3 cm of its length out of water. If it is 15 cm long and 4 cm in cross section, calculate the weight of they cylinder.
I'm not making it up, honest.
Mollie
Assuming that "4cm in cross section" actually means 4 square centimetres, then:
The portion submerged, and therefore the volume of the water displaced, is 12cm X 4cm^2 = 48cm^3
One cc of water weighs one gramme, and a floating object displaces its own weight, therefore the cylinder weighs 48 grammes.
If on the other hand "4cm in cross section" means 4cm squared then:
The displacement is 12 X 16cm^2 = 192cc = 192 grammes
I'm truly surprised that anybody can answer these questions nowadays. I bet our 15 yr olds nowadays can't. I've no idea whether the answerw given are right but ice seems pretty confident.
So, definitley the last one:
A ladder AB, 50 ft long has its end A on horizonal ground and rests at a point C on the ladder against the top of a vertical wall 25ft high, so that the end A makes and angle of 50 degrees with the ground. The end A is now moved 9ft towards the wall along the ground. What will be the height of end B above ground level? (Give your answer to the nearest foot)
I truly can't imagine our kids being able to do things like this

I can do the Pythag part in my head, but I'd need tables for the trig, which I haven't got.
