2. Strength: Strength is the resistance against failure. A good timber should not fail easily and it should be strong enough to take loads acting on it. The strength of timber varies depending on the direction (transverse or direct) it is loaded. Strength is considered as an important property while designing structural wood members such as wooden beams, joists, rafters, etc.
3. Permeability; The permeability of timber should be less. A good timber should not absorb more than 8 to 12% of water by its weight when placed in water. The water permeability of timber depends upon various factors such as moisture content of timber, age of timber, type of timber, type of cut, etc.
