Answers:
(Denote counterclockwise moments with positive values; clockwise moments with negative values. Denote upward or rightward forces applied to the beam at A with positive values; downward or leftward forces applied to the beam at A with negative values. Report only a force magnitude (positive) for the reaction at E.)
