Question
Q2).During an experiment on a timber specimen 70 mm x 70 mm in cross-section, a shortening of0.45 mm was recorded on a gauge length of 350 mm when a load
of 46 KN was applied.Calculate the modulus of elasticity of the timber. Using this value of E, determine the amount of shortening of a timber post 150 mm square and 3.2 m high due to an axial load of185 KN.
