What floats your boat.

The whole thread needs to be put on ice in the deep-freeze. If only to save Tom the embarrassment ! I know some said Einstein was wrong, but......if we can't take dear old Archimedes' principle as "settled", there would be little we could.

 

I actually assign them to do Dave Cockey's calculation. But by giving them a box barge the computation - over the entire underwater surface of the hull - is simple.

Now, try repeating the calculation for a box that is sitting on the bottom, such that there is no water between the bottom of the box and the seabed.

 

Regarding post #5

The one with the most area in contact with the water will have the lest draft.

Using website information.
Buoyancy force Archimedes principle of buoyancy.
_This means the more area you give a material the higher it can ride in the water.


_When an object floats it displaces, a volume of water whose mass is equal to the objects mass. If it can`t displace this much water the object sinks.

Lesson Closure.
_But the shape of the object can determine how much water will be displaced by the object.

My comment.
A flat bottom boat is not necessarily a shallow draft boat.

 

Regarding Post #33.

No. You are wrong. Stop.

 

I'm inclined to say a flat bottom boat gives the shallowest draft possible, everything else is deeper.

 

This is a discussion on what floats your boat if I am wrong prove it with sensible discussion not acting like naughty school children.

 

C'mon the last sentence can be true!

 

I presume the information on the web is wrong according to your theories.
Prove it.

 

Shape is not volume! If you crush your boat flat it will have the same perimeter but not the same volume, if that's what you mean......and so what?

 

A Myark folding trailer barge with a 13 ton digger on top floating in 12" of water.

With no load on top it floats in 2" of water and plans with 50hp outboard at 20 knots.

All the information is true if you accept the teaching of the teachengineering site is correct.
Come on boys loosen up. I have never met a competent " Engineer " yet.

 

Here is the way to show that area is important.

 

Draw any other non-flat hull shape that will have less draft than the barge pictured given equal weight, beam, and length.

You are getting desperate.Do you not accept the information on teachengineering as being correct.
What fun we have with our children at school.Who would want to be a reacher.

 

myark, everyone here knows what floats yer boat.....
