The beam AB is subjected to the uniformly distributed load shown and to two unknown forces P and Q. Knowing that it has been experimentally determined that the bending moment is + 2.7 kN ∙ m at C and + 2.5 kN ∙ m at D when a = 2 m,
(a) Determine P and Q,
(b) Draw the shear and bending-moment diagrams for the beam.
