Explanation:
Detailed explanation-1: -Compression or shear strength of a wood beam or truss used extensively for construction can be calculated based on the following equation: Sigma () = P/A, where is stress, P is load and A is surface area.
Detailed explanation-2: -Characteristics of compression wood include eccentric growth rings, a high percent of latewood per ring, higher density, intercellular spaces, helical checking of the cell walls, a large microfibril angle in the S2, and a higher lignin content.
