To quickly assess the difficulty of the text, read a short excerpt:
If the plates be 6" wide, and T = 3J" (which is re garded as in good proportion, the above formula gives L == 2J" very nearly, for a f " hole. Then, 5" being allowed for the space ce, and 2" each for cd and eg, the splice plates would have a length of 20J", and { of the whole section of chord plates would be available for tension; since an oblique section through two holes, would quite equal a direct transverse section through one hole.
The amount of rivet section above given is estimated upon ...the assumption that each rivet must be sheared ARCH TRUSS BRIDGES. 197 off in two places; and that it will resist, those shear ings, each, with about f of the force required to pull the rivet asunder by direct longitudinal strain.
It is obvious that the two rivets e and/, Fig. 34 J, sus taining a portion of the stress of the chord plate, relieve in the same degree the stress upon the portion between those rivets and the joint, or end of the plate ; whence it is not necessary to preserve the same section in the portion thus relieved, as in other portions of the plate.
