@Vs Fan as you say max B.M wl^2/12 it is wrong because for SSB carrying with UVL max B.M is wl^2/(9*(root3)) at the location l/(root 3) distance from minimum thickness end.

While finding bending moment diagrams some time we take w as per unit length while sometimes it's used as w per metre length.

Bending moment Wl^2/12 maximum at the centre, shear force 0 at centre.

No, for gradual load your answer is also right @Joel.

If its point load then answer may right.

If the point load the answer is wl/8.
