Curves of Form, TPC, MCT & Bonjean Integration
Inside this lesson
- Describe what curves of form are and how they're generated
- Read hydrostatic values from a table at a given draft
- Define TPC (tonnes per centimetre immersion) and compute it from waterplane area and density
- Use TPC to estimate the draft change from a known weight addition
- Define MCT 1 cm and use it to estimate change of trim from a trimming moment
- Describe Bonjean curves and use Simpson's rule to integrate sectional area along the ship's length
