A barge has a uniform rectangular cross section of width 2L
A barge has a uniform rectangular cross section of width 2L and vertical draft of height H as shown in Figure 5.1. The centre of gravity, G, is at the waterline height. Figure 5.1: Schematic of a floating rectangular hull. If L = 2.5m and H = 1.85 m which ONE of the following statements about the metacentric height (GM bar) and the barge\'s stability is TRUE? GM bar = 0.20m, unstable GM bar = 0.20m, stable GM bar = -0.20m, unstable GM bar = -0.20m, stable
Solution
The barge becomes unstable only when G and M coincide and also for negative values
So we can say GM value should be positive enough for stable
Option B
