A **truss** of straw contains 36 lb, of old hay 56 lb, of new hay 60 lb.

The singular Colossus bridge, built in 1812 over the Schuylkill, a kind of flat arched **truss**, had a span of 340 ft.

In the form of boxes with top and bottom plates, side plates, and angles with proper stiffening bars on the side plates, or " I's," or lattice, or other forms of **truss** work.

The Howe **truss** of 1830 and the Pratt **truss** of 1844 are examples.

In the Pratt **truss** the struts were vertical and the ties inclined.

20 shows a Fink **truss**, a characteristic early American type, with cast iron compression and wrought iron tension members.

- It is convenient to consider beam girder or **truss** bridges, and it is the stresses in the main girders which primarily require to be determined.

65 shows a common form of bridge **truss** known as a Warren girder, with lines indicating external forces applied to the joints; FIG.

When caught by a gust of c, c, Thin bands of iron with **truss** planks a, a, and wind, actually lifted the d, d, Vertical rods.

**Truss** rods, portals, or lattice or plate girders constitute the more definite types of wind-bracing ordinarily employed; the bracing must reach to some solid connexion at the ground.

The Howe **truss** had timber chords and a lattice of timber struts, with vertical iron ties.

As railway loads increased and greater spans were demanded, the Howe **truss** was stiffened by timber arches on each side of each girder.

On twice the vertical projection of one **truss**, no train being supposed to be on the bridge.

A multiple **truss** consists of a number of simple **trusses**, e.g.

A frame used to support a weight is often called a **truss**; the stresses on the various members of a **truss** can be computed for any given load with greater accuracy than the intensity of stress on the various parts of a continuous structure such as a tubular girder, or the rib of an arch.
