Isn't it annoying...

[Terry Smart]

..that you've opened this thread only to find there's nothing here that interests you?

 

[mailee]

Good God Terry, you must be bored. :lol: Mind you what does that make me reading this? :lol:

 

[Gill]

It's always nice to hear from you, Terry (as Nicholas Parsons might say).



But it's not worth a bonus point.

Terry, will we see your smiling face on Friday/saturday you know where?

 

[ike]

no...(i'm not annoyed)

 

[ByronBlack]

This is quite an interesting thread, Terry, why not tell us about yourself? What was your most recent nightmare?

"opening a thread, only to find nothing of interest!!" :lol:

With intent on making it interesting :lol:

If I drilled two holes using a forstner bit 1" dia, one hole is exactly 1" deep the second hole is 1/2" deep, do I have 1 and a 1/2 holes or two holes? :lol:

Now me really try to be irritating.

I assume most people know what a LOCK is (think Boats, the invention to raise or lower a ship)

Now think of a big lock that would take 10,000,000 gallons to raise it from the lower level up to the higher level.

Which would use or waste the most water to lock up from the lower level to the higher level?

A) A ship that almost fills the lock .
B) A small motor boat (say less than ten tons)
C) No boat at all (they sometimes have to fill the lock when a boat is waiting to lock down)

:evil:

 

[matt]

"use or waste"? None would actually use or waste the water.

 

[DomValente]

Now, I've lost interest and the will to live :?

Ok I'll rephrase it.

A) A ship that almost fills the lock .
B) A small motor boat (say less than ten tons)
C) No boat at all (they sometimes have to fill the lock when a boat is waiting to lock down)

Think we need to phone a friend :wink:

pity Archimedes is not available :lol:

 

[NeilO]

OK LN, i`ll bite :lol:

I would have to say "C", given the laws of displacement..

A, would need the least amount of water, being as the ship almost fills the lock anyway..

B, comes in second place , as the smaller boat would not displace as much as the larger vessel.

C, would need to be filled completely with water, in order to open the lock.

or do I just know F**k all about locks and boats :lol: :lol:

 

[TonyW]

They would all need the same amount :?:

Cheers
Tony

 

[ByronBlack]

I would also say C - no displacement by the hull of the boats.

Oh, and you first question, you don't have either a big hole or two holes, you have concentric hollow rings.

Trivia:

You're in a car with your wife, you break down in the woods late at night, you leave the car locked to get help, when you come back there is another person in the car with your wife. Who is that person, and how did he/she get there? (no there is no damage to the car, it isn't a convertible and your wife cannot open the doors or windows, and it remains locked).

 

[Nick W]

They're all the same.

Think of it like this:-
1) Close the gates
2) Lift the water that is already in the lock (plus any boat that may be there) vertically until the surface is level with the higher reach of water
3) Fill the gap that is left underneath that lot with water.

your son/daughter (well hopefully) she was pregnant when you broke down , and had the child whilst you went for help??
