Fig. 132
The above diagram ([fig. 132]) illustrates the supports and loading of the beams just considered. The following diagrams show beams variously supported and loaded, and their relative strength to the first. By adding to the formulæ already given, the proportion that these following bear to the first, the same formulæ can be used for all.
Fig. 133
Beam supported at both ends and load equally distributed bears double of [fig. 132].
Fig. 134
Beam fixed, load in centre, bears half more than [fig. 132].
