Download file to see previous pages The terrain of the ground can be described as flat since there was no any steepness was observed. On the east side of the site, walkway was present while buildings were not within the vicinity of the site as shown on the map.
Before the excavation of trial pit the top soil was removed. The next step was to place all the layers of soil according to their extraction order. This was very important as the characteristics of the soil at different depth would be established. Tests such as Moisture Probe test, the Mackintosh test, shear vane test and the permeability test were conducted to establish the properties of various strata. The results of these tests revealed that;
This test is aimed at measuring the ability of the soil to sustain structural load. This test is essence for the purpose of putting up a building in the site. The test first measure the un-drained shear strength by planting a shear vane into the ground and measures the level of pressure at the point where the soil shears as shown on table 3.
We settled for the mackintosh probe because it is portable due to the fact that it is hand operated in addition it produces vivid and reliable results. The test used a 5Kg hammer to drive a number of connected 120cm-long steel rods into the ground at intervals of 100mm. The depth of the result was as in table 4. Reading from the table, it can be inferred that there is a distinct intensification in the quantity of blows between 400 and 500mm. The result affirm that the soil gets denser as the ones penetrates to the ground.
Permeability (k) is the ease with which water passes through the soil. It is measured in ms-1.cylinders of 100mm in diameter and 150mm in height are planted into the ground and filled with water. Measurements are then taken every minute of the water level as it decreases with time (flow rate). On the matters of reliability the test is questionable as there might be some ...Download file to see next pagesRead More

Machines

...?Ergonomics is mainly concerned about the design of machinery in accordance with the capabilities of human body in order to optimize the productivityof human beings and machines through an efficient relationship and interaction between the two. There are various different limitations to the way human body can work, a working environment that is best suited to the human body can generate productive results. The development of machines exactly in accordance with the limitations of human body is very difficult; similarly humans cannot use a machine to its highest efficiency because the limitations of human body and capabilities vary from one individual to the other. There are other factors...

Machinery Planning Exercise

...activities that will take place at the farm, a number of different machinery will be necessary. As a professional in the agricultural field, I would recommend the following for the farm or land owner. The soil in the farm is loamy hence soft. Because of this, the purchase of a sub-soiler and the plough will put into consideration the purchase of a machine with higher speed value. The farm is an extensive farm where manual labour cannot be exclusively employed. For this reason, the machinery becomes necessary in the provision of service as a form of mechanization certain machinery will be needed for planting, soil cultivation, harvesting, sorting, irrigating and fertilizing among other...

Braiding Machines

...Braiding Machines The technique of braiding fibre is an old technology used in manufacturing a vast range of products such as cables, insulators, and surgical sutures. After discovering the high tolerance of braided structures to damages and their conformability, braids are now being used to produce composites for rocket launchers and aircraft structures (Peters, 1998 p 413). Adanur (1995) describes a circular braiding machine as one which is made up of two sets with even number of spools that contain braiding yarns. One set of yarn runs in a clockwise direction around the centre of the machine, while the other yarn set turns in a counterclockwise direction. While the yarn sets revolve in two opposite directions, the carriers... are...

Hydraulic Machines

...of the vane = Work done per second Kinetic energy per second Operating principles of common turbomachines Introduction Turbomachines or turbines are defined as the hydraulic machines which convert hydraulic machines into mechanical energy. This mechanical energy is used in running an electric generator which is directly coupled to the shaft of the turbine. If the water flows parallel to the axis of the rotation of the shaft, the turbine is known as axial flow turbine. If the head at the inlet of the turbine is the sum of pressure energy and kinetic energy and during the flow of water through runner a part of pressure energy is converted into kinetic energy, the turbine is known as reaction...

Can machines think

...Can machines think? Section Number of Can machines think? The Oxford English Dictionary defines the word ‘think’ in its verb form as (1) be of the opinion, (2) judge or consider, (3) exercise the mind positively with one’s ideas, (4) consider; be more mentally aware of, (5) form or entertain the idea of; imagine to oneself, (6) choose mentally; hit upon, (7) have a half-formed intention, (8) form a conception, (9) reduce to a specified condition by thinking, (10) recognize the presence or existence of, (11) intend or expect and (12) remember. The process of ‘thinking’ is defined as ‘using thought or rational judgment.’ The complexity of the process of thinking is evident in the very fact that the meaning of the word ‘to think’ can... be...

Thinking machines

...CHAPTER 4 QUALITATIVE CONTENT ANALYSIS Purpose of the Paper As the use of machine increases, so do the scope of their utility and the strength of their capabilities. With computers and robots trying to achieve human-level intelligence, human kind have often paused to consider whether machines have actually gained the capability to think. ‘Can machines think?’ is a question posed by the famous British mathematician and computer scientist Alan Hume Turing who proposed the Turing Test to gauge the thinking capability of machines or computers. This paper examines the questions from different perspective and endeavors to come to a definite conclusion on whether...

Hydraulic Machines

...of mechanics which relate continuity of mass and energy with force and momentum together with solid mechanics properties. Hydraulic machines are those machines which convert hydraulic energy into mechanical energy (further converted into electrical energy) or mechanical energy into hydraulic energy. The former types of machines are called turbines and the latter, pumps. Impact of a Jet onto a vane A combination of both pump and turbine is used in fluid couplings and torque converters for the transmission of power smoothly through a fluid medium. The analysis of impact of fluid jets on vanes is typically involved in the design of an efficient turbo-machine. When a vane...

Soil concentration

...Soil Concentration Elemental composition that is found in soils has anomalies leading to plant stress, as well as increased salt concentration (Cl-), and Ca2+ mineral nutrients. The salt concentration found in soil solutions is measured in form of its salinity. The amount of Cl- present in a given soil solution determines its salinity, which is required for proper plant life. Cac2+ is an important mineral nutrient in soil for plant life, but is harmful if in excess. The main cause of soil salinity can be attributed to the water management practices used on a given soil solution. High concentrations of Cl- destabilize...

Soil order

...Soil order and their associated environmental climates Arid soil Soil order The soil orders of arid soils are always free-draining. However, these soils receive insufficient rainfall due to the climate and it is for this reason that they always retain their soluble salts. The order of arid soils is characterized by three levels which are: Oxisol Vertisol Entisol It is however important to note that not all arid soils are classified in the aridsol order. Some have unique compositions that place them in other orders of soil. Oxisols are weathered soils found in the...
