The change in trim of a vessel may be found by __________.
A. dividing the trim moments by MT1
B. subtracting the LCF from the LCB
C. looking at the Hydrostatic Properties Table for the draft of the vessel
D. dividing longitudinal moments by the displacement
A. dividing the trim moments by MT1
B. subtracting the LCF from the LCB
C. looking at the Hydrostatic Properties Table for the draft of the vessel
D. dividing longitudinal moments by the displacement
The best answer is A. "dividing the trim moments by MT1" although I think their real intention was to refer to the Total Trim Moment should be divided by the MT1 in Imperial Units or MTC in Metric Units.
ReplyDeleteChoice B. is a detractor to confuse you. There is no practical result when you subtract the LCF from LCB.
Choice C. will only yield you a draft at the LCF for the assumed trim the hydrostatic tables are calculated. The question asked for Change of Trim not Draft.
Choice D. will only result in calculating LCG, which is not what we are looking for.
A. Change in trim = trimming moment / MT 1
