A brief description of the failure and the nature of any defects is entered on the log sheet.
[Illustration: FIG.

32 .-- Sample log sheet, giving full details of a transverse bending test on a small pine beam.] _Calculating the results_: The formulae used in calculating the results of tests on small rectangular simple beams are as follows: 0.75 P (1) J = -- ------ b h 1.5 P_{1} l (2) r = -- ----------- b h^{2} 1.5 P l (3) R = -- ------- b h^{2} P_{1} l^{3} (4) E = -- ----------- 4 D b h^{3} P_{1} D (5) S = -- ------- 2 V The same legend is used as in BENDING LARGE BEAMS.

The weight of the beam itself is disregarded.
ENDWISE COMPRESSION _Apparatus_: An ordinary static testing machine and a compressometer are required.
