Question
Bunyan Lumber Co. needs to create a table of the engineeringproperties of its lumber. The dimensions of the wood are given asthe base and the height in inches. Engineers need to know thefollowing in formation about lumber:cross-sectional area: (base)x(height)
moment of inertia: (base x height3) /12
section modulus: (base x height2) / 6
The owner makes lumber with the base sizes of 2, 4, 6, 8, and 10inches. The height sizes are 2, 4, 6, 8, 10, and 12 inches. Producea table with the appropriate headings to show these values and thecomputed engineering properties. The first part of the table'soutline is shown.
