A rectangular pontoon 10m long, 7m wide and 2.5m deep weigh 700kN. It carries on its upper deck an empty boiler of 5m diameter and 600kN weight. The centre of gravity of boiler and the pontoon are at their respective centers alongthe vertical line. Find the metacentric height. Take sp. wt. of sea water as 10kn/m^3 .
stability in least Moment of inertia ===> MI in longitudinal axis is more ( ie 5m== pitching direction ) than lateral direction ( ie 3m ==rolling ) because if stability occurs in lateral direction it obviously stable in longitudinal direction

Why you calculate moment of inertia about Y-Y axis? Why not about X-X axis?
Sir here depth is 5 and breadth is 3 u solved in opposite way in case of moment of inertia
Madhurima Madhu I guess it should be (1.2*3^3)/12.. correct me if I'm wrong!
hmm mai b vahi soch rahi thi
nd sir toh RK bansal seedha chaap rahe hai.....samja b nhi rahe aise toh book pe b dekh saktey thai

sir -lecture is very good and short - please write big -thank u sir
Great work sir aise he accche acche videos banao sir har topic pe..really heplful for my sem exam.Thankyou..
Why in 1:35 time. Does he write: 5*(3)^3/12 = 45/(4) ----- four? or fourteen?
sahi toh hai bhai , (5*27)/12
Why are you using top view to find moment of inertia ????
becouse, tilting axis can see in top view, which is y axis
idk
how to calculate when the hull shape is semicicrle or v shape
thankyou for everything ....
GM=BM-BG
How did you get 12 on 5x3³/12?
rectangular moment of inertia equation (bd^3)/12
It's bd^3/12
Is the metacentric height always same, no matter how it rotates?
no, the metacentric height will change for larger angles of heel.
Thx sir
❗Is there numericals on buoyancy and metacentre will be ask in ssc je or not❓❓❓❓❓❓❓❓
idk
Holy units Batman!
Sir can you say me how the AB is .4
Bocoz b is centre point of floating box from a to water is 0.8 then half of the 0.8 is 0.4
How ab=0.4 can any one explain
Buoyant force acts at centre of immersed part, here immersed part is 0.8 m now half of it is 0.4
thank u sir it helped me alot
not good lack of details.
Then you should improve your students skill of intaking, everything was clear, I watched on 1.75 x and was able to catch every single detail
@@Purrfect_Toons i hope you can touch it too. hahaha
Can we take I along other axis?
no, it is swinging about Iyy .
idk
