The center of flotation of a vessel is __________.
A. the center of volume of the immersed portion of the vessel
B. the center of gravity of the water plane
C. that point at which all the vertical downward forces of weight are considered to be concentrated
D. that point at which all the vertical upward forces of buoyancy are considered to be concentrated
A. the center of volume of the immersed portion of the vessel
B. the center of gravity of the water plane
C. that point at which all the vertical downward forces of weight are considered to be concentrated
D. that point at which all the vertical upward forces of buoyancy are considered to be concentrated
"B." Is the best answer.
ReplyDeleteIt has been argued a plane has only two dimensions with no thickness, so you could say it has no center of gravity!
DeleteOver the years choice "B." has been the classic illustration of the LCF, because students were asked to simily cut out the area of the waterplane using a piece of cardboard and then using a pin to find the balance point to illustrate the location of the LCF.
"B" is the best option.
ReplyDeleteHaving discussed the topic over the years, I believe that the following definition better describes the centre of flotation - geometric centre of waterplane area
B. the center of gravity of the water plane.
