A timber specimen of 40.33 mm width,70.07 mm depth and 604mm length and its weight is 798.9g carried loads(kN):
4,6,8,10,12,14,16,18,20,22,24,25.7.
and deflection(mm)
0.44,0.87,1.34,1.81,2.29,2.79,
3.39,4.17,5.42,7.21,11.02,21.94
please,
1-find density of timber.
2-determine maximum load that can be taken before deflection become or the failure if the failure occurs before maximum deflection is reached.
3. calculate the failure stress and young modulus for beam
