Response:
I agree with TDoT's answer.  You wrote "Fs ·sin18°" but computed "Fs·cos18°".

</Off-topic rant on>
BTW I welcome TDoT's hand sketching and writing. This is the way we write up homeworks, take-homes, exams, etc, so IMO we should do the same on the Board.  I wish some SME's here would spend more time on the accuracy of their solutions (check equilibrium and hypotheses) than on fancy drawings and equation typesetting.  As rookies we partly rely on you, voluntary experts, to show us not only the best way to become efficient but also the tricks to produce solutions that will stand up to scrutiny by our peers.  In the meantime, thank you all.
