A section of a $3ft$ diameter and $5ft$ long birch log $($SG $=0\mathrm{.}71)$ falls and acts as a dam for seawater as shown in the figure. The height of the water $H=10ft$ reaches the top of the log$.$ The weight of the log acts at $b=1\mathrm{.}05in$ from the vertical diameter. Find if the log is stable about $A,$ by calculating the moment $lb-ft$ about A$.$ Assume counterclockwise moment to be positive.
