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.

Bars AD and CE (E=105 GPa, a = 20.9×10-6 °C) support a rigid bar ABC carrying a linearly increasing distributed load as shown. The temperature of Bar CE was then raised by 40°C while the temperature of Bar AD remained unchanged. If Bar AD has a cross-sectional area of 200 mm² while CE has 150 mm², determine the following: the normal force in bar AD, the normal force in bar CE, and the vertical displacement at Point A.

Draw the updated network. Calculate the new project completion date. Check if there are changes to the completion date and/or to the critical path. Mention the causes for such changes, if any. New network based on the new information received after 15 days (Correct calculations, professionally done). Mention if critical path changes or extended. Write causes for change in critical path or extension in the critical path.
