Question 135Safety & Environmental - Assistant Engineer

The correct answer is B) Simpsons Rule. Simpsons Rule is a commonly used mathematical formula to calculate a vessel's water plane area for stability purposes. It is a numerical integration method that provides an accurate approximation of the area under a curve, which in this case is the vessel's water plane. This formula is widely recognized and used in naval architecture and maritime engineering to determine the stability characteristics of a vessel. The other answer choices are not the standard formula used for this purpose. Reynolds Number Rule and Standard Logarithmic Rule are not directly applicable to calculating water plane area, while the Pythagorean Rule is a general geometric formula unrelated to the specific task of determining a vessel's water plane area.
