I got the idea of weight placed at centre of flotation and moved from here LESSON TOPIC:...

This was an idea that Phil Sweet had, I based calculation in Engineering Stack Exchange from that. I agree with you on centre of gravity, so it...

Hi Heimfried Yes I see what you mean, you have used difference in volume and trim angle and change in draft = change in volume / waterplane area....

Hi Adhoc Thanks for the reply. This is the quoted question from my Solving Problems in Fluid Mechanics Volume 1 by J F Douglas. I see what you...

Hi Ad Hoc Just wondering if you managed to get some spare time to look over my question that I have not found the answer to. This is from a...

I have these images from google search that might help HOLLOW cylindrical shells - Google Search...

I'm still confused how to deal with the fact that the centre of gravity is 20mm aside from the vertical centreline. From your transfer of weights...

That's fine just when you have some spare time I have actually put this question on delft ship forum as well called "Placement of cargo from...

Hi TANSL The other day I went through this question and this is what I came up with First calculate Depth of Oil in Tank 45,000 litres is 45...

My answer of 60.32 minutes for the first part of the question when pontoon floats freely relates to the horizontal distance from the vertical...

No it's not homework, so this is not to assist me with a qualification. I am interested in naval architecture and have a hobby on the side,where I...

Normally you would added the two second moment of area together, but in this case it is a bit different. One of the tanks is empty and the other...

I'm an amateur trying to learn about naval architecture and I'd appreciate your help.

Hi Heimfried I've looked at the question and it was definitely the same as in the book. The book is Solving Problems in Fluid Mechanics Volume 1...

I am trying to workout how to arrive at the answer for the following question. A rectangular pontoon is 12m long, 4.2m broad and 2.1m deep and it...

I am trying to workout how to arrive at the answer for the following question. A hollow cylinder 2.4m high consists of two concentric cylindrical...

I am trying to workout how to arrive at the answer for the following question. A tank barge of unladen weight 1000 kN is 24m long, 4.5m wide and...

Thanks for your reply. Are you able to show with a calculation how this works for this question? With GM (L) do you mean the metacentric height...

I have tried to work out this question myself. I have taken into account the change of draft in sea water from parallel sinkage and trimming...
