5th progress report
I. OBJECT OF THIS REPORT The full program of tests outlined at the meeting of the Technical Subcommittee held in Ithaca on June 12 has been carried out with one exception: due to the limited time it has not been possible to determine the modulus of elasticity of the sheets. However since the modulus of elasticity of steel under any circumstances is about 29,000,000 to 30,000,000 p.s.i. this point of the program has no immediate practical significance. The following tests have been carried out: 1. Tests to failure of the remaining specimens of the series B - 22. 2. Determination of the yield point, the ultimate strength and the permanent elongation of the sheets from which the beams tested have been formed. 3. Investigation of the stress distribution in the bottom flange at and in tIle vicinity of the load points of the last received specimens of series C - 22. Investigation of the stress distribution at and in the vicinity of the load points of the specimens of the first series A - 14. 5. Tests to failure of one specimen of each type of the series A - 14. 6. Tests to failure of one specimen of each type of the last series C - 22.
