Question

Explain how density affects the machining properties of wood​

Answer 1

As discussed in Lesson 1, density is an excellent indicator of wood strength; the higher the density the stronger the wood. However, a wood with a density of 600 may not be twice as strong as one with a density of 300.

The properties are good at all sizes of material wherever it is homogeneous

What size affects is the likelihood there are flaws in that piece of material. Smaller objects have less likelihood of flaws and come out stronger than big pieces. Big stuff with flaws breaks into smaller stuff missing those flaws so the smaller stuff is less likely to break. Example Aircraft cable is stronger than a solid rod of the same material.
