So cried he, and, plunging into the thick of the affray, smote aside all such as barred his way until he fronted Sir Pertolepe, who, astride a powerful mailed charger, wielded a bloody mace, and who, hearing that hoarse cry, turned and met the shearing axe with blazoned shieldand behold!

Their age also, particularly of the rams, is reckoned by the number of times they have been shorn, the first shearing taking place in the second year; a shearing, or one-shear, two-shear, &c.

Every one is familiar with the sheep-shearing scene in Thomson's "Seasons:" "Heavy and dripping, to the breezy brow Slow move the harmless race; where, as they spread Their dwelling treasures to the sunny ray, Inly disturb'd, and wond'ring what this wild Outrageous tumult means, their loud complaints The country fill; and, toss'd from rock to rock, Incessant bleatings run around the hills.

Then your Aunt Hattie's hens are so obliging that they keep me from the worry of finding ticks at shearing time.

(3) The development of heat is greatest where the shearing of the material is strongest.

This shearing is therefore the mechanical cause which produces the heating effect.

The mechanical properties of wood considered in this book are: (1) stiffness and elasticity, (2) tensile strength, (3) compressive or crushing strength, (4) shearing strength, (5) transverse or bending strength, (6) toughness, (7) hardness, (8) cleavability, (9) resilience.

cit., pp. 57 et seq.] SHEARING STRENGTH

Whenever forces act upon a body in such a way that one portion tends to slide upon another adjacent to it the action is called a ~shear~. In wood this shearing action may be (1) ~along the grain~, or (2) ~across the grain~. A tenon breaking out its mortise is a familiar example of shear along the grain, while the shoving off of the tenon itself would be shear across the grain.

In addition there is a shearing force tending to move the fibres of the beam past each other in a longitudinal direction.

Shearing across the grain is so closely related to compression at right angles to the grain and to hardness that there is little to be gained by making separate tests upon it.

{ P } { Shear = - } { A } Oblique shearing stresses are developed in a bar when it is subjected to direct tension or compression.

It is often due to shake or season checks, common in large timbers, which reduce the actual area resisting the shearing action considerably below the calculated area used in the formulæ for horizontal shear.

For this reason it is unsafe, in designing large timber beams, to use shearing stresses higher than those calculated for beams that failed in horizontal shear.
