1)Absolute Max +ve Shear

enter image description here

$ SF= 80 \times 1+60 \times \frac{16}{18}+80 \times \frac{14}{18}+100 \times \frac{11}{18}$

$SF= 256.67KN$


2) Absolute Max -ve Shear

enter image description here

$SF= -[80 \times \frac{11}{18}+60 \times \frac{13}{18}+80 \times \frac{15}{18}+100 \times 1$

$SF=-[258.88]KN$


3) Absolute Max B.M.

enter image description here

$By \hspace{1mm} Varignon's \hspace{1mm} theorem$

$80 \times 3+60 \times 5+80 \times 7=320 \times …
