Explanation:
Detailed explanation-1: -7. How should be the colour of good quality timber? Explanation: Heart wood consists of dead cells which are free from sap, hard, dark in colour. Hence, dark coloured wood is preferred.
Detailed explanation-2: -The tensile strength of soft-woods parallel to grain at 12% moisture content generally ranges between 70 to 140MPa. The compression strength is lower and is usually in the range 30 to 60 MPa. For hard-woods, these values are generally higher. These values are for clear, straight-grained wood samples.
