Daily License Questions about Ship Stability and Trim: I just think people need to have some knowledge in their heads, professional or otherwise. After 2007 our world has changed due to the advent of Smart Phones. Retaining knowledge is like being able to play a musical instrument, if you do not use it you will lose it! The questions I post with will hopefully help you keep what you already know or remind you of what you should know. William E. George
If G equals ctr of gravity, and M equals metacenter, the distance between the two is called metacentric height. Aka GM.
ReplyDeleteI agree.
DeleteI agree, I think it is B. GM
ReplyDeleteYes, B is the only answer.
ReplyDeleteGM always refers to "Metacentric Height"
On the other hand "Height of Metacenter" refers to KM. (KM = KB + BM). Hold onto this thought for later in this comment.
"BM" is referred to as Metacentric Radius which equals the (Moment of Inertia of the Water plane) / (Diaplaced Volume). So at light drafts BM is very large Wich makes KM very large so the GM of a vessel at its lightest draft is the greatest.
"M" is the position of the Metacenter.
"GZ" is Righting Arm or Righting Lever or on Computers it is the "HBG".
Do you agree to disagree with my comment? Keep in mind any vessel or floating object can have two sets of hydrostatic properties: transverse for stability, longitudinal for trim.

Agreed!
ReplyDeleteHave you thought about asking your questions in the form of a Poll? That way the votes for each answer would be tabulated, with the discussion down in the comments.
Just a suggestion, really appreciate and enjoy the discourse here!
The idea about using a poll format is good. I tried it once so far with a small response, however this is a different format than my old LinkedIn Groups. I will try it again. The polling questions appear in the right column on computers, on phones the view is different. Thanks.
