The first years or so of the United States’ existence was filled with travesties like the Civil War and the enormous slave trade which flourished in the South. In addition, manifest destiny and the inherent racism involved with the “white man’s burden” led to a number of horrible massacres of the Native American population.

NAIL-WITHDRAWAL RESISTANCE OF AMERICAN WOODS 1 By Forest Products Laboratory, Forest Service U.S. Department of Agriculture Resistance of a nail to direct withdrawal from a piece of wood is intimately related to the density or specific gravity of the wood, the diameter of the nail, and the depth it has penetrated.

The values given herein are for nails driven perpendicular to the grain of the wood. When the nail is driven parallel to the wood fibers --into the end of the piece -- withdrawal resistance in the softer woods drops to75 or even 50percentof the resistance obtained when the.

When the nail is driven parallel to the wood fibers -- into the end of the piece -- withdrawal resistance in the softer woods drops to 75 or even 50 percent of the resistance obtained when the nail is. Nail Withdrawal Strength of Plywood and OSB Objectives It is well known that the resistance of a nail shank to direct withdrawal from wood-based materials is a function of several factors, including material density, nail diameter, and depth of penetration (FPL, ).File Size: KB.

They determined that nail withdrawal resistance at static nailing is higher than dynamic nailing. They concluded that nail withdrawal resistance decreases with time in the density of wood in both nailing types.

It was also found that the nail withdrawal resistance is maximized for tangentially nailing by: Although the equation for nail-withdrawal resistance indi-cates that the dense, heavy woods offer greater resistance to nail withdrawal than do the lower density ones, lighter species should not be disqualified for uses requiring high resistance to withdrawal.

has low nail-withdrawal resistance but has little tendency to split under the action of nails or screws. It's easily worked and fairly easy to finish to a smooth surface.

It was the real story of the Resistance - and I hadn’t heard much positive about them. This account puts things in perspective. Good s:   A new testing apparatus was designed and a test method developed to enable the application of axial loads, lateral loads, and controlled ratios of axial to lateral loads to nailed wood joints.

The effect of axial load components on ultimate lateral load, joint deformations and several slip moduli were evaluated. These load-slip parameters were determined for three species of wood, three depths Cited by: 9. Example - Nail Withdrawal Load.

My library. ASTM's wood standards are instrumental in the evaluation and testing of the physical and chemical properties of a wide range of wood and wood-based products. Wooden materials covered here include timber, lumber, wood-base fibers, commercial softwoods and hardwoods, wood preservatives, laminated timber, and composite lumber to name a few.

The nail withdrawal resistance and wearing resistance showed a similar trend. The MOE seemed to be an exception. After heat-treatment, the MOE values of undensified and densified wood were decreased by 15 and 24%, by: Six selections from the book (under the title "A Massachusetts Hermit") appeared in advance of publication in the Ma issue of the New York Daily Tribune.

RE: Nail withdrawal capacity for wind uplift BlastResistant (Structural) 6 Mar 10 I don't have any problems with nailing directly into plywood sheathing or using NDS nail withdrawal values, but I do have a problem with the actual nail withdrawal values themselves.

The National Building Code of Canada (NBC) provides prescriptive guidance for fastening typical wood-frame construction. At the same time, the Canadian Standards Association (CSA) O, Engineering Design in Wood, provides rational mechanics-based analysis methods for engineered design.

Both of these resources rely on CSA B, Wire Nails, Spikes, and Staples, as the reference. The withdrawal resistance of a nail driven into the end grain of a wood member is. A. Lower than the withdrawal resistance when driven into the side grain.

B. The same as the withdrawl resistance when driven into the side grain. C. Greater than thewithdrawl resistance when driven into the side grain. D. Greater than the shear resistance.The authentic art of Indian bow-making is explained and illustrated by Al Herrin, a Cherokee Indian in his book "Cherokee Bows and Arrows".
