Mechanical Energy

Electrical generators are used to produce electricity by converting mechanical energy (energy created by a motorized or automated system) into electrical energy. So as to power up some device that relies on electricity; power generator is the more generic term used for any system that uses some mechanism to create power.

Many power generators make use of diesel in order to maintain their mechanical process; this generates a great deal of pollution and is also not a readily accessible option in different parts of world, where diesel and other fuels are too costly, or too difficult to gain access to.

Diesel remains an industry standard though because it comparatively cheap, does the job effectively especially when considered in light of its cost, as well as the low fire hazard it poses, such reasons are exactly why petrol is very rarely used. Typically, all internal combustion generators produce major volumes of carbon monoxide, an extremely toxic gas as well as being rather noisy.

Fuel cells are now beginning to make a major push in the market as a result of their innovative design. Fuel cells differ from normal power generators in a major way, in that they produce power by producing electrons directly, (thus achieving the end result of electric energy without the need for mechanised, kinetic energy process.)

This poses a number of advantages, they produce almost no noise, and require much much less maintenance because of the reduced number of mechanical pieces. Best of all, they do not require any oil or fuel at all!

In a bid to find a more environmentally friendly, eco-conscious and effective way of producing power, a great deal of money and research has been committed to so call “renewable energy sources”. Some of the more readily known examples include the likes of solar powered generators as well as wind turbines, with wind-powered generators currently a firm favourite.

So how do these wind powered generators (also known as turbines) actually work then? Well, they make strategic use of natures very own resources: the wind, as well as the sun. The sun, heats our atmosphere in a very disorganised and random manner, meaning that different layers of the atmosphere are warmer, others cooler.

The segments of the atmosphere that are warmer begin to rise and climb in altitude, and as they make their ascent, the cooler parts of the atmosphere then begin to also move to take their place. This creates the sensation we know as the wind.

The wind powered generators are designed like a giant fan on a large “stalk”, as the wind blows the propellers of the fan, this kinetic energy is then converted into electrical energy which can be used to power any sort of electrical equipment.

A major drawback to this method of power generation is that it requires areas that are predominantly windy anyway, so apart from coastal areas, and plains as well as higher altitudes, such generators are not much use. However, solar power energy is steadily being worked upon and finessed, and has also resulted in a major increase in awareness for the need for renewable energy supplies.

If you’re looking to install new hardwood floors, you’ve probably come across technical specifications having to do with the wood’s hardness, density, and other characteristics. These mechanical properties may make perfect sense to hardwood industry insiders, but to the average homeowner they may as well be written in Latin. Knowing what these measurements mean, however, can help you better understand the type of hardwood flooring you are interested in and whether it is suitable for the room in which you intend to install it. Here are a few key hardwood mechanical properties, what they measure, and why they are important – all in plain English.

Hardness: Often called Janka hardness, this specification measures how resistant a wood species is to indentation. The test involves measuring the pounds of force required to embed a small ball (11.28 mm, or.444 in.) into the wood a distance one-half of its diameter (5.64 mm, or.222 in.). Janka hardness is measured in pounds, and the larger the number the harder the wood. For instance, exotic Ipe has a Janka hardness of 3,680 lbs., while domestic Douglas Fir has a hardness of only 950 lbs. Hardness is important if you are installing the wood in a high-traffic area, or if the wood will support heavy furnishings, such as entertainment centers or pianos.

Modulus of Rupture (MOR): Also referred to simply as Strength, the MOR refers to the measure of force that is required to break the wood. In other words, it is the wood’s load-carrying capacity. The MOR is measured in pounds-per-square-inch, or psi. The higher the psi, the stronger the floor. Like hardness, MOR is important to know if you plan on placing heavy furnishings on your new floors.

Modulus of Expansion (MOE): Also called Stiffness, the MOE is a measurement of the wood’s stiffness or resistance to bending. MOE is also measured by pounds-per-square-inch and, because of the intense force required, is expressed in exponential terms. For instance, the MOE of Douglas Fir is 1,950,000 psi, expressed as 1,950 1000 psi. The MOE is an important indicator of whether your floors will buckle. The higher the MOE, the less likely the wood will be stretched and buckle.

Density: The density of a hardwood is related to its weight and hardness, and should be considered similarly. Measured in KG per cubic meter (KG/m3), density tells you how much of the wood is packed into a cubic meter. The higher the density, the heavier and harder the wood will be. A higher density isn’t always better, especially if you are installing floors on a second or third story. Density is also a good indicator of a wood’s natural resistance to water and termites. The denser the wood, the harder it is for water and boring insects to get in.

Tangential Shrinkage: This property refers to how much a wood species tends to shrink during the drying process. It is expressed as a percentage and applies only to the width of the plank or board. The shrinkage factor is a good indicator of how much your wood floors may warp or buckle – the lower the percentage, the more stable the floors.

Radial Shrinkage: Similar to tangential shrinkage, radial shrinkage tells you how much the wood species may shrink through the thickness of the board. It is also expressed as a percentage. A low percentage is good, but what’s more important is the combination of these two measurements. The closer the two are to each other, the more stable the wood. For instance, Maple has a tangential shrinkage of 9.9%, and a radial shrinkage of 4.8%. The differential is 5.1. Walnut, on the other hand, has a tangential shrinkage of 7.8% and a radial of 5.5%. Even though Walnut’s radial shrinkage is higher than Maple’s, the differential of Walnut is 2.3 – much lower and therefore less likely to warp or buckle.

Many of these hardwood mechanical properties can be confusing, and some industry insiders even struggle with the concepts. However, knowing the basics of what they measure and why they are important will help you pick the perfect hardwood species for your flooring or decking needs.
