member. Remember that the stress to be provided for at the bottom of a vertical post is not the stress on the post itself, but the algebraic sum of the vertical components of the stresses in all diagonals attaching to the pin at the foot of post, or, approximately and on the side of safety, the stress on the post plus one half of a panel-floor load. See that no bar diverges from the central plane of truss more than one eighth (1/8) of an inch to the foot.

See that fillers are shown and their sizes given wherever they are necessary to hold the members to exact position on the pins.

Check all pins for the greatest bending moments coming on them, determining the same by combining the bending moments in two directions at right angles to each other.

Sixth. See that the centre-of-gravity lines of all members are shown; and where any such line is not in the central plane of member, see that it is located from the side of the section.

Seventh. Wherever a drawing is either wholly or partially shown in section, see that the exact point at which the section is taken is indicated in writing, and that the section line is properly shown on the other views to which the note refers.

Eighth. Compare all sections of members and all leading dimensions with those on the stress-diagram, and see that they correspond thereto.

Ninth. See that all stay-plates and lacing-bars are shown, and that the sizes for same are given; also that these sizes comply with the requirements of the specifications. The inclinations of all lacing-bars should be given.

Tenth. See that all extension-plates of forked ends are carried at least six inches inside the end stay-plates, and that they are strong enough to develop the full strength of the main member, even though the computed stress be small.

Eleventh. See that all reinforcing-plates at ends of members are so distributed as to balance as nearly as practicable the bearing on the two sides of the main section.

Twelfth. Compare drawings which show the same details, so as to make sure that all are alike.

Thirteenth. See that the same style of detailing has been
