What are the 4 distortions commonly found in board lumber? - Answer Cupping (along the width of the board), Bowing (along face), Crooks (along the edge) and twisting occur along the length. What does "bark side up" refer to when laying decking boards? - Answer Laying decking boards with growth rings facing down and with the convex side up, preventing the board from entrapping water. What is the optimum moisture content for lumber stability in a structure? - Answer 12% What 5 pieces of...

These notes offer a comprehensive guide to the theory needed to write final exams in matric. They contain all the information about electrolysis in the IEB chemistry syllabus. They are typed in a column format for easy learning. They have an array of diagrams to aid learners in their physical science studies in grade 12.

1. If the roof and ceiling assembly of a structure has a factor of thermal conductance (U-factor) of 0.04, what should be the R-value of the insulation used in this same assembly? A. 2.5 B. 10 c. 25 D. 40 1. C. The answer is 25. The U-factor is the thermal conductance of one square foot of an entire assembly. The reciprocal of U is R, which is the thermal resistance of the same square foot of construction. A U-factor of 0.04, therefore, corresponds to an R-value of 1/0.04 = 25 (choice C). ...
