Second Moment of Area for a Ship's Waterplane
Loading the math board and drawing, please wait…
This example demonstrates the calculation and visualization of the second moment of area for a ship's waterplane shape. It involves core mathematical concepts such as integral calculus, vector operations, 3D spatial geometry, and standard deviation. The construction leverages the Sum command and objects like pic1, A1-A12, B3-B12, C3-C12, D3-D7 for summation and geometric representation. It is suitable for university students in naval engineering, mechanics, or advanced mathematics as a practical application of calculus and 3D geometry.
