Which of the below type of timber has Young’s Modulus greater than 9800 N/mm^2, but less than 12600 N/mm^2?(a) Average timber(b) Very good timber(c) Good timber(d) Light timberI have been asked this question in an online interview.This intriguing question originated from Classification of Timber in division Materials for Construction of Basic Civil Engineering

Answer»

The correct CHOICE is (c) Good TIMBER

Easiest explanation: Average timber has Young’s Modulus (E) VARYING between 6600 N/mm^2 and 9800 N/mm^2.Very good timber has E GREATER than 12600 N/mm^2.There is no CLASSIFICATION as light timber based on E.
