A $6-$ft$-$long fishing rod $AB$ is securely anchored in the sand of a beach. After a fish takes the bait, the resulting force in the line is $6\mathrm{.}2$ lb $.$

Determine the moment about $A$ of the force exerted by the line at $B.($Round the final answer to one decimal place.$)$

The moment about $A$ of the force exerted by the line at $B$ is $($lb$.$ft$)$i $+(lb*ft$lb$.$ft$)$k$.$
