From bending moment to laminate

A simple and crude way to calculate the laminate thickness of the mast is to assume the mast is an I-beam.

For the graph below I also used the following assumptions:

-Righting moment of the yacht is 60 kNm (see previous posts);

-The mast is an I-beam with 100 mm wide flanges;

-A safe maximum stress (compression/tension) in the carbon laminate is 200 N/mm2.

The graph shows the carbon laminate should be more than 10 mm thick around the upper bearing ( 0 m ).
