Sample log sheet, giving full details of a transverse bending test on a small pine beam.
Calculating the results: The formulæ used in calculating the results of tests on small rectangular simple beams are as follows:
| 0.75 P | |||
| (1) | J | = | -------- |
| b h | |||
| 1.5 P1 l | |||
| (2) | r | = | ------------ |
| b h2 | |||
| 1.5 P l | |||
| (3) | R | = | --------- |
| b h2 | |||
| P1 l 3 | |||
| (4) | E | = | ------------ |
| 4 D b h3 | |||
| P1 D | |||
| (5) | S | = | --------- |
| 2 V |
The same legend is used as on [page 98]. The weight of the beam itself is disregarded.
ENDWISE COMPRESSION
Apparatus: An ordinary static testing machine and a compressometer are required. ([See Fig. 33].)
