Questions from Capt Subramaniam's Ship Stability are used as examples for student understanding. Students are advised to watch the previous videos (links below) before watching this video. 1) Ship Stability (Volume, Mass, and Density): https://www.youtube.com/watch?v=zD0ezi2wq1s&t=5s 2) Ship Stability (Pressure and Thrust): https://www.youtube.com/watch?v=P-ewJnMd0Fo&t=108s 3) Ship Stability (Displacement and Under-water volume): https://www.youtube.com/watch?v=e7Jt8MY93VQ&t=43s 4) Ship Stability (Deadweight, TPC, and Reserve Buoyancy): https://www.youtube.com/watch?v=5Kaz-n5edwg&t=271s 5) Ship Stability (Load lines, effect of density on draft and displacement): https://www.youtube.com/watch?v=-NyQorOxcTE&t=1467s 6) Ship Stability (Shift in the centre of gravity and KG calculation): https://youtu.be/-zHEJ7AYWiU 7) Ship Stability (Centre of Buoyancy): https://youtu.be/X5R7NLues5M 8) Transverse statical stability of ships: https://youtu.be/1jrjQTibIb8 9) Equilibrium of ships and Angle of Loll: https://youtu.be/MdwkZ1a5BNA 10) Calculate free surface correction on ships: https://youtu.be/9z5pYiWUBHA 11) Calculation and correction of ship’s list: https://youtu.be/tV28-XaGcmg 12) Extra questions on ship’s list calculation and correction: https://youtu.be/Ll8q8P4aXD4 13) Hydrostatic tables (Part 1): https://youtu.be/2lN4eHw3PDg 14) Hydrostatic tables (Part 2): https://youtu.be/N3exrv28xxk 15) Hydrostatic draft: https://youtu.be/SzfexEI_5G8 16) KM and BM calculation: https://www.youtube.com/watch?v=kDIBo8fDJ18 17) KM curves drawing and calculation: https://youtu.be/C-BEhptIrCw 18) Simpson’s First Rule: https://www.youtube.com/watch?v=rZ6A4lj8Kac 19) Simpson’s Second Rule: https://youtu.be/RYfBtWZQTKs 20) Combination of Simpson’s First and Second Rule: https://youtu.be/05yqp6WjKNw 21) Simpson’s Third Rule: https://youtu.be/-uO_wQXCpDg 22) Calculate volume using Simpson’s Rules: https://youtu.be/ZQfvTYB6NOI 23) Fresh water allowance: https://youtu.be/1ajzBCOgavs 24) Angle of Loll: https://youtu.be/3BbL4X-tABs 25) Calculate centroid using Simpson’s Rules: https://youtu.be/Q2RTNxDYsn4 26) Curve of Statical Stability: https://youtu.be/g5DdSSMYa-Q 27) Cross Curves of Statical Stability: https://youtu.be/SOkwlijrTOA 28) KN curves: https://youtu.be/ucEHQEsx_Kw 29) Trim Problems (Part 1): https://youtu.be/UXh-k1WCX8c 30) Trim Problems (Part 2): https://www.youtube.com/watch?v=Fj_F2m9tDnY&t=1s 31) Trim Problems (Part 3): https://youtu.be/SlrlnZvE-yo 32) Angle of loll correction: https://youtu.be/31_KZl-JgXQ 33) Increase in draft due to list: https://youtu.be/UCWaexmoc6Q 34) Combined list and trim: https://youtu.be/Jtq_ax-qerw 35) Combined list and trim: https://youtu.be/4SfMC1lAjMc 36) Drydocking Problem 1: https://youtu.be/hts2cHp6Qmw 37) Drydocking Problem 2: https://youtu.be/46FMCviT7vE 38) Drydocking Problem 3: https://youtu.be/nZEKDFszuIg 39) Bilging Amidships (Theory and Numerical): https://youtu.be/UxxCDmoMVTI 40) Bilging amidships (Example 2): https://youtu.be/pljRuAHb_Hg 41) Permeability (Theory and numerical): https://youtu.be/FjuMpM6osYs 42) Permeability (Example 2): https://youtu.be/HAV8CjnFdkg 43) Vessel’s heel due to turning: https://youtu.be/OMYccmcXzXA 44) Application of moment of inertia: https://youtu.be/o0NtgBSq-RU 45) Stability of passenger ships in damaged condition: https://youtu.be/IEp-0cSbNak 46) Severe wind and rolling period diagram: https://youtu.be/7GFLxSjGrK4 47) GM by rolling period tests: https://youtu.be/Fz2G64SdW6s 48) Calculate GM by means of rolling period tests: https://youtu.be/UZOMJun_3gM 49) Passenger vessel requirement for turning: https://youtu.be/ihvyz8yK89A 50) Inclining experiment: https://youtu.be/JFzxMKGwUZQ 51) Bilging of end or intermediate compartment: https://youtu.be/NbkGQb0Xp88 52) Shearing forces and bending moments: https://youtu.be/9Ww4wFera7g 53) Change of trim due to change in density: https://youtu.be/AJmGbd3D3Jc 54) Achieving desired draft at one end: https://youtu.be/DrZHBdIONk4 55) Achieving desired trim at one end: https://youtu.be/OyGDJxCm3qQ 56) Achieving desired trim at one end (example 2): https://youtu.be/2ZUcZvVKnPU 57) Achieving desired draft at one end (example 2): https://www.youtube.com/watch?v=xXI_xiuOGo0 58) Grounding (Loss of GM) calculation: https://youtu.be/W9pk57szIVA 59) Dry Docking calculation (MV Hindship): https://youtu.be/ylN2JoExYSw 60) Q.24 from M.V.
