Compaction Test on Soil

Compaction Test on Soil

Introduction      Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. Compaction test is principally performed on soil is to reduce the settlement that happens when the soil is subjected to load from the structure above it. Compaction helps in increasing the shear strength of the soil. It reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used…

Introduction to Mechanical and Transmission Drives

Introduction to Mechanical and Transmission Drives

Introduction For power to be transmitted from one machine to another over a distance there is need for a transmission mechanism. Therefore, mechanical drives are mechanism which is intended to transmit mechanical power over a certain distance usually involving a change in speed and torque. For this to happen there is need for a prime mover called the driver such like electric motor and a machine to be driven, such as threshers, grinding machine, extractors, de-hullers to mention but a…

Determination of Some Physical Properties of Biological Materials

Determination of Some Physical Properties of Biological Materials

Some of the physical properties of agricultural produce include the following: Shape indices Moisture content The moisture content is discussed HERE . Now we shall focus on the shape indices of Agricultural materials. Determination of Some Shape Indices of Agricultural Materials Introduction      One of the physical properties of Agricultural material is what is called the shape index. Shape index is how the material in question looks like in physical, talking about the shape, the length, breadth and height of the material. Moreover,…

Determination of Moisture Content of Agricultural Produce

Determination of Moisture Content of Agricultural Produce

Introduction      Moisture content in simple terminologies means water contents; it is the amount of water found in any agricultural produce. Many of the agricultural produce harvested from field has some level of moisture present in them and we need to determine the amount of water they possessed before we can determine how to handle, process and store them. Moisture content has been the major reason while some agricultural produce get spoilt most of them leading to what we call agricultural…

Determination of Coefficient of Static Friction of Agricultural Produce

Determination of Coefficient of Static Friction of Agricultural Produce

Introduction to Coefficient of Static Friction      In order to design Agro-processing machine effectively, the study of the physical and mechanical properties of seed and grain is essential for optimal machine design, selection, and operation (Faleye, T. et al).      The coefficient of static friction is one of the important practical to be carried out if one needs the understanding of mechanical properties of any agricultural materials. The coefficient of static friction is defined as the friction overcome by any agricultural material…

Determination of Angle of Repose of Agricultural Materials

Determination of Angle of Repose of Agricultural Materials

Introduction to Angle of Repose      In the processing, handling and storage of agricultural produce, “granular materials” means Grain, fruit and seeds and these granular materials possesses frictional properties (Mohsennin 1978). AссоrdÑ–ng tо (Ogbоnnауа and Fаtаі, 2007) thе rapid method оf аѕѕеѕѕіng thе behavior of grаnulаr mаѕѕ is bу thе dеtеrmÑ–nаtіоn of “angle оf rероѕе”.     If a solid is poured on to plane surface, it will form an approximately conical heap and the angle between the sloping side of the…
