# Stability – I : Chapter 6

###### Solution:

Given:-

Weight = 8800t,
Original KG =6.2m,
KG = 1.7m

###### VM
8800 t 6.2m 54560tm
(+) 200 load 1.7m Final VM  54900 tm

Final W – 9000 t                                               Final VM  54900 tm

So, we can calculate

Final KG = (Final VM/ Final W)
Final KG = (54900 / 9000)
= 6.1m

Here ‘VM’ stands for vertical moments.

###### Solution:-

Given:-
Weight =12600 t
Original KG =6m
Cargo discharged  = 600 t,

Cargo discharge 11 m above the keel

###### VM
12,600t   6m 75,600tm
( -) 600t ( discharge) 11m  (-) 6600tm

Final Weight =12000 t                               Final VM =69000tm

We know that :

Final KG         =        (Final VM / Final Weight)

Final  KG         =          ( 69,000 / 12000)

= 5.75m

###### VM
12,600t    4m 39,600tm
(+)100 t  load  15m  ( +)1500tm

Final W 10000t                                             Final VM =41000tm

We know that:

Final KG         =        (Final VM / Final Weight)
Final KG        =   ( 41000 / 10000 )
=   4.11m.

###### Solution:

Given:-

Weight = 11500t
Initial KG = 6.3m
Cargo discharged = 500t, KG =3m
