Book excerpt: Excerpt from Suggestions for the Improvement of Old Bank Dairy Barns Very frequently heavy beams are placed with the lesser dimension vertical, an uneconomical practice originating with the use of tree trunks adzed on two sides to provide bearing surfaces. There is a rough rule that doubling the width of a 'given timber doubles the strength, but doubling the height increases the strength four times. A square timber is often used when one of less width but greater height and of less cross-sectional area would carry the same load. Thus an 8 by 12 inch beam with the 12-inch side vertical will carry 21' per cent more than a 10 by 10 inch beam, yet the former contains 4. Per cent less material than the latter. If the beam were placed with the 8-inch side vertical it would support but three-fourths as much weight as the 10 by 10 inch beam. The true overshot construction - that is, without posts or piers under the outer wall - makes very expensive storage for hay or straw. The heavy cantilever beams required are an uneconomical form of support because of the size of the beams and the substantial anchor age that must be provided at their inner ends. 'beams supported at the outer ends require much less material and erection labor. A comparison of the two principles is shown in Figure 7.
