![]() In: Soil Physical Measurement and Interpretation For Land Evaluation. Please refer to Bulk Density-On Farm Use fact sheet for information on interpreting bulk density results and using this in total nutrient and carbon calculation.Ĭresswell HP and Hamilton (2002) Particle Size Analysis. Both the intact clod and excavation methods are described in detail by Cresswell and Hamilton (2002). The excavation or water replacement method is useful for soils that are too loose to collect an intact core or clod, or for soils containing gravel. This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur. If soil has >10 % gravel or the stones are >2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.2–3.0 g/cm 3 (McKenzie et al., 2002). Total pore space is reduced in soil with abundant gravel and plants are more susceptible to the effects of drought and waterlogging. The presence of gravel has a significant effect on the mechanical and hydraulic properties of soil. It is generally desirable to have soil with a low BD (2 mm) are the coarse fragments and gravel. Both BD and porosity (V pores) give a good indication of the suitability for root growth and soil permeability and are vitally important for the soil-plant-atmosphere system (Cresswell and Hamilton, 2002 McKenzie et al., 2004). Soil BD and porosity (the number of pore spaces) reflects the size, shape and arrangement of particles and voids (soil structure). The average values of air, water and solid in soil are easily measured and are a useful indication of a soils physical condition. The total soil volume is the combined volume of solids and pores which may contain air (V air) or water (V water), or both (figure 1). The soil bulk density (BD), also known as dry bulk density, is the weight of dry soil (M solids) divided by the total soil volume (V soil). Bulk density can be used to calculate soil properties per unit area (e.g.Sandy soils are more prone to high bulk density.Bulk density increases with compaction and tends to increase with depth.Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth.Bulk density is the weight of soil in a given volume.This is the ratio of the density of a substance compared to the density of pure water. The density is derived by dividing the mass of a quantity of substance by its volume. This is the measure of the amount of mass per unit volume of a substance. ρ 0 = Density of pure water (1000 kgm -3 SG = Specific gravity (e.g.The conversion formula used by this tool is: The density will be displayed as a specific gravity ratio in the lower text box.Select the corresponding mass and volumetric units from the upper pair of selection boxes to define the density measurement units.Enter the density value to be converted in the upper input box.A conversion scale showing SG values for a range of density values will also be displayed, which will change according to the entered density. This calculator will compare the substance density you have entered with the density of pure water and display the result as a specific gravity decimal ratio. ![]() If you're only going to be doing it once or twice, it might be worth considering an online tool.

![]() Using a glass bottle in clouds emitted when the ender dragon breathes or shoots a dragon fireball fills the bottle with dragon's breath. However, a lingering potion use on tipped arrow recipe does not give the bottle back. Honey bottles can also be emptied by using them in crafting recipes (such as sugar or honey block). If a bee nest or beehive is full, the player can use a glass bottle on the block, or may power a dispenser that contains a bottle and is pointed at the block, which empties the block and creates a honey bottle. When the bottle is filled, 1⁄ 3 of the cauldron's potion is removed. In Bedrock Edition, a bottle may be filled with potion by using it on a cauldron containing potion. Therefore, using a cauldron to fill water bottles is inefficient, except in the Nether where it is normally the only way to fill bottles. If filled via a cauldron, 1⁄ 3 of the water in the cauldron is removed. If filled via a water source, the water is unaffected. It can also be filled using a waterlogged block. Īlso, a bottle may be filled by powering a dispenser containing a bottle and pointed at a water source block. Glass bottles are also used to hold the resulting potion.Ī bottle may be filled with water by holding it in the hand and using it on a water source block or a cauldron that has water in it. Glass bottles can be filled to make water bottles, which can then be used to brew items with a brewing stand. Using a water bottle (or, in Bedrock Edition, a potion, splash potion, or lingering potion) on a cauldron that is not yet full adds that liquid to the cauldron, leaving the player with an empty glass bottle. ![]() Using a water bottle, splash water bottle or lingering water bottle on dirt, coarse dirt or rooted dirt will transforming it into a mud block, at the same time leaving the player with an empty glass bottle. This is increased by 3 per level of Looting, for a maximum of 0–15 glass bottles. Witches have a chance of dropping 0–6 glass bottles upon death.

![]() In view of the structures, the development of the original crossbow can be divided into Unearthed trigger mechanism was found in Qufu in Shandong Province, and it can be dated back to the 6th century BC (Zhong, 2008). The original crossbow is The Art of War dated from 498 BC (Needham, 1954). In the Warring States Period (475–221 BC), it There are a lot of ancient documents which recorded informationĪbout the original crossbow. In the Spring–Autumn Period (770–476 BC), the original crossbow had been widely used. WesternĬrossbows are often complex, and several moving parts must have been fabricated. The characteristics of Chinese crossbows are that the parts are easy to re-assemble and are exchangeable. Around the 16th century AD, it spread to Africa and the Americas. Of Eurasia, and more Asian than European. The crossbow is fundamentally an implement of warfare ![]() Long periods of time and being inaccurate in shooting (Zhang et al., 2004 Human force, thus remedying the two issues of people being unable to aim for This development improved the bowstring which previously had to be pulled by Tightened the bowstring, it facilitated the aiming and shooting of arrows. Trigger mechanism onto a traditional bow. It was developed by adding the frame and a This could beĭescribed as a developed weapon which used the delayed force of the bow'sīowstring to shoot arrows. In ancient times, an original crossbow was called a “nu”. People's interest in hunting implements continued to develop over the nextįew thousand years, and this influenced the development of human projectile Progressed from throwing stones to using bows and arrows in hunting. Therefore, it is widely believed that prehistoric people's behavior Many arrowheads have been excavated which are made from stones or animalīones. In addition, in ruins dating back to the Neolithic Age, In ruins, stoneĪrrowheads have been unearthed, dating from 1.7 million years ago to 10 000 years ago. The original crossbow evolved from the traditional bow. Two crossbows are presented to illustrate the shooting processes. Proposed to check the constrained motion. The degrees of freedom of two crossbows are Then, topological structures of the original crossbow and Chu State Provided as an example to describe the manufacturing process of the bow. A brief history of the development of the crossbow in ancient China is given. Matrix to present the topological structures of the original crossbow and It is defined as a reconfigurable mechanism. Of the crossbow has a different configuration during the shooting process, After the 4th century BC, the technology of producing crossbows was very sophisticated. Because it used theĮlasticity of the bow and the bowstring to shoot arrows, it was used for It was one of the most frequently used weapons during theĥth century BC to the 18th century AD. I have therefore removed the incomplete PDF documents, leaving only the complete PDF originally provided by user El Supremo.In ancient China, people integrated the original bow, theīowstring, and a cam mechanism to develop a powerful weapon which was named I have also looked back at the original book I scanned this from, and realized (thanks to a commenter) that I managed to skip two pages of the original article in my scans.

I made a few PDF files of this, and you can find them at (link removed). Anyway, I just thought this might help some of you people wanting to build a crossbow! :) The metal on the front of the smaller crossbow could be replaced with something else, such as a thick strip of plastic. Some of it is outdated, but I'm sure there is a way to fix that. These are some old DIY crossbow plans from the 1945 edition of "The Boy Mechanic". |
