The breaking strength of a beam of wood is determined by bending the sample in a (preferably) 4-point bending apparatus. The 4-point test ensures an uniform bending force between the two inner points.
A 3-point test has an unequal bending force between the two outer points, but is more indicative of non uniform defects in the beam.
All of this testing on defect free samples, and under appropriate moisture and temperature conditions.

∙ 10y agoWood can be more or less dense than plastic. Which is heavier depends on the different types of plastic and wood being compared, and how much of each is present. Often, however, wood is heavier than plastic for the same amount of material.
Wiki User
∙ 13y agoThere are different types of wood, with different densities; and there are different types of plastic, with different densities. In general, I would say the densities are roughly equal.

∙ 15y agoIt depends on the thickness of the plastic it could be stronger of course so could the aluminum

Why does wood burn quickly when put on a fire that is already blazing?
Because heat is a big factor in starting and keeping a fire. You have air, and fuel, and the heat is already factored in. The wood that is already there burning helps too because the fact that it is burning means that most of the wood is dry, and dry wood burns much faster than wet or damp wood. Plus, the dry burning wood dries out any new wood that is placed on top of it, making all of the wood dry, which is the same as stacking tinder, as it is already ready to be set ablaze.

Why are dry wooded areas at high risk of fire in the hot season?
dry wood is easily caught on fire. When wood is wet it cant catch fire. That's why when you make a camp fire you want dry wood. It lights easier and burns better.
If a water slide was dry how would the friction be different?
Water can absorb friction because it's wet and slippery. When things are dry, there nothing slippery or wet to absorb the friction, so the friction becomes stronger.
