Johan Baptist Spanoghe (1798, Madras – 22 April 1838, Pekalongan, Java) was a Dutch botanical collector of Belgian parentage.
A native of Madras, then part of British India, in 1816 he became a civil servant with the Dutch East Indies government. In 1821 he was named as an "assistant resident" for the southern divisions of the Bantam Residency in western Java. From 1831 to 1836, he was stationed on the island of Timor.
As a botanist in the East Indies, he collected plants in Java, Timor and neighboring islands, and also in Bali. The genus Spanoghea was named in his honor by Carl Ludwig Blume, who for a period of time, worked closely with Spanoghe in Java.
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways.
The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment and deflection
in the pictured beam is found using:
where
Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the stress) will quadruple, and deflection will increase by a factor of sixteen.
For long-distance rope spans, used as power line, antenna or for aerial tramways, see list of spans.
