Page 247 - Material which is to be used without annealing or further treatment shall be tested in the condition in which it comes from the rolls. When material is to be annealed, or otherwise treated before use, the specimens for tensile tests representing such material shall be cut from properly annealed or similarly treated short lengths of the full section of the bar. 10. At least one tensile and one bending test shall be made from each melt of steel as rolled. In case steel differing jú-in. and more in...
Page 15 - The most perfect system of rules to insure success must be interpreted upon the broad grounds of professional intelligence and common sense.
Page 85 - You will also read there that we are fully aware of the fact that there is still a great deal to be learned about the treatment of schizophrenics.
Page 169 - The flanges of plate girders shall be connected to the web with a sufficient number of rivets to transfer the total shear at any point in a distance equal to the effective depth of the girder at that point combined with any load that is applied directly on the flange. The wheel loads where the ties rest on the flanges shall be assumed to be distributed over three ties.

Page 261 - All pins and small parts must be securely boxed and the boxes plainly marked, The weights of large pieces must be marked on them. The invoices shall state...
Page 167 - The flange plates of all girders must be limited in width so as not to extend beyond the outer lines of rivets connecting them with the angles, more than five inches or more than eight times the thickness of the first plate. Where two or more plates are used on the flanges, they shall either be of equal thickness or shall decrease in thickness outward from the angles.
