The beam shown below is subjected to only two types of loads: live load W₁ = 0.7 k/ft, and dead load WD =

1.5 k/ft. Based on the ASCE 7-16 basic load combinations, determine the following:

(1) maximum factored negative moment Mu at support B

(2) maximum factored negative moment Mu at support D

(3) maximum factored positive moment Mu at section E (mid-span of DF)

(4) maximum factored shear Vu at the immediately right side of section D
