I have one statics question on SFD&BMD.
"5) A Shear Force and Bending Moment diagram for an uniformly supported beam is given as follows, Find the actual loading pattern for this beam. Total beam length is 12 m and middle portion is of 6 m, where shear force decreases from 4.5 kN to -4.5 kN. Hint: Look at the symmetry of the diagram."
The picture of the diagram is at http://kinimage.naver.net/20120702_129/13411593150153JCrJ_PNG/%C1%A6%B8%F1_%BE%F8%C0%BD.png?type=w620
