To determine

The four common types of lumber used for framing and different qualities of structural lumber by using internet.

Expert Solution & Answer

Explanation of Solution

Southern pine (SP #2), Douglas fir−larch (DFL #2), Hemlock-fir (Hem-fir #2) and Spruce-pine-fir (SPF #2) are the most common forms of framing lumber. #2 is applied to each species. The number refers to the species grade value. Only #1 or #2 grade lumber is commonly used as framing lumber.

The different qualities of structural lumber are as follows:

Durability: Strong lumber should be sufficiently durable to withstand the acts of physical agencies, biological agents, chemical agents etc.
Strength: Resistance to failure is strength. A good lumbershould be strong enough to bear loads that act on it and should not collapse readily.
Hardness: The resistance to penetration is hardness. Strong lumber should be workable and robust.
Toughness: The resilience to unexpected shocks and vibrations is toughness. A strong lumber should be solid enough to withstand sudden vibrations and impact loads.
Structure: The lumber is said to be a fine lumber if it has a uniform structure. lumber fibers should be firm and straight.
Defects: It is said that a lumberis fine if it is free from defects caused by natural forces such as shakes, knots, burls etc.
Fire resistance: lumber fire-resistance is very weak. Dense lumber provides the most fire resistance of all forms of lumber but only up to some constraints.
Mechanical wear: pavements, floors, etc. made of lumber are continually exposed to traffic loads. Therefore, strong lumber against abrasion or mechanical wear does not easily deteriorate.

Students have asked these similar questions

The rectangular gate shown in figure rotates about an axis through N. If a=3.3 ft,b=1.3 ft, d=2 ft, and the width perpendicular to the plane of the figure is 3 ft, what torque(applied to the shaft through N) is required to hold the gate closed?

An elevated tank feeds a simple pipe system as shown. There is a fire hydrant atpoint C. The minimum allowable pressure at point C is 22 psig for firefighting requirements.What are the maximum static head (in ft) as well as pressure (in psig) at point C (i.e. nodischarge in the system)? Do we meet the pressure requirement for firefighting? (Please donot worry about L or d in the figure below)

12. For the beam loaded and supported as shown, determine the following using Point Load Analogous via Integration: a. the rotation at the left support. b. the deflection at midspan R1 1 . m 600 N/m 3 m + 2 m R2
