1. Are the values obtained from tests on smaller beams applicable to beams of larger size? Explain.
2. Is modulus of elasticity in bending the same as in compression or tension test ? Explain.Would you expect it to be higher or lower? Why or why not?
3. Discuss the relationship between the modulus of rupture of a small wooden beam and the ultimate compressive strength of a short block loaded parallel to the grain.
4. How does the speed of load application affect the observed strength?
5. Conclusion

Solution
1)No. Values obatined from the smaller beams are not same as that of larger beam.
It\'s deflection if different. For larger beams more deflection will be there.
If deep beams are there then deflection will be less.
Shear force and B.m will be same
