Question: a bookshelf of length 2l is to carry a uniform...

Question details

A bookshelf of length 2L is to carry a uniform row of books of weight w per unit length, and is supported on two simple supports at a distance a from each end. The shelf may be treated as an elastic beam. If the supports are close together then the largest bending moment is hogging over the supports, and if they are near the ends of the beam the moment is greatest in sagging at the centre. 9. a) Find the position of the supports to give the same magnitude of bending
moment at the centre and over the supports. b) Calculate the magnitude of the bending moment with the supports in this position.
