report 1

This plot is known as the grain distribution plot and will be used for purposes of this report. More often, a relatively distributed curve shows well graded or a soil which is poorly sorted whilst an extremely steep distribution curve, a curve with steep distribution shows poor grade or sufficiently sorted soil. Objectives of the experiment This lab was developed to determine the distribution of grain size for Concrete & Asphalt materials. This is achieved by determination of the coefficient of uniformity,, as well as the coefficient of curvature, . These describe general slope and shape of the curve respectively for the grain distribution curve. Consequently, how good or poorly sorted a given soil sample is can be obtained using and. The equations are as shown below; , showing the coefficient of Uniformity; and , which shows the coefficient of Curvature As per the equation D10 represents the size of the grain size where 10% of soil sample passes, as shown in the grain size distribution curve. D­30 and D60 correspond to size of the grain size whereby 30% and 60% by weight of sample of the soil passes through. D10 also refers to effective size. Grain size as well as distribution is vital given that it directly affects stability of slope as well as the soils drainage abilities. ...

Summary

Sieve analysis Name: Institution: Date: Introduction Sieve analysis is a process applied on coarse grained soil in order to establish the distribution of the size of the grain. As the sample of soil under investigation goes progressively via the consecutively smaller sieves, the weight percentage of the sample collected in each of the sieves is calculated…

The first type is the Total Station, which is classic equipment and is not only a GPS system. The other two types of equipment used are the Trimble Juno SB handheld and Leica antenna. These two types of equipment are used in similar ways to position points, but the Leica antenna is more accurate and expensive. On the other hand, the Trimble is cheaper than the Leica antenna. This report will show how the devices can be used and a comparison between all three based on the results each type of equipment’s accuracy. Aim: To understand how GPS systems work by using different types of equipment,...

Engineering - Steel Report
According to Degarmo and Black (2003, p.56), reinforced bars with high ductility and tensile strength are often preferred because they allow the materials to be rolled, drawn or made longer without breakage. Generally the tensile strength of reinforcing steel can be measured by dividing the cross sectional area of the steel tested by the stress exerted on the material. The amount of stretching force (N) needed to break the test material can then be measured and recorded. Experimental Procedure The tensile testing experiment involved calculating mechanical properties of three specimen samples...

The resultant signal is channelled into the powered amplifier. The role of the power amplifier is to drive the loudspeaker. The circuit is designed such that the mixer contains a gain that can be varied, depending on the desirability of the required volumes. In addition, there should be the allowance for the volume of one channel to be controlled separately from another. This enhances the quality of sound as this enables one to have balance between the two channels. In this regard, the presented diagram consists of a set of two inputs; the speech and music. In this case, the speech voltage...

However some technical problems such as weight of the arm and unforeseen parameters of the robot going out of the maze were encountered in execution of the project. The objective of the project is to enable a robot to look for a ball and pick it up while avoiding black lines. The goal is divided into a logical sequence that enables the robot to achieve its goal. The sequence flow is as follows. The necessary parameters for the robot are set, these include the sensors and motors that enable the robot to move. The robot then looks for a ball. It then estimates and determines the distance to the...

CTV Building Collapse: Case Report
A number of investigations were carried out to figure out the causes of the building collapse and all the investigation reports pointed to poor building design and construction operations. The principal engineer Alan Reay employed an inexperienced engineer (David Harding) for the building design. In addition, Reay did not supervise the operations of Harding and hence many potential defects in the construction process had gone unidentified. To worsen the problem, the construction manager failed to properly guide the building’s foreman. The Christchurch City Council issued a permit for this...

Used to restrict flow through the line. Used to control the velocity of fluid within the piping. Extensively used to measure flow rate within the piping. Orifice in the form of orifice plates is widely used for injecting constant flows to the apparatus. They are vital part of electronic fuel ignition systems where metered amount of fuel is injected within the combustion chamber through orifice, as they provide very stable flow. Orifices used for such critical applications are designed with great effort. They must be smooth enough to reduce frictional effects which greatly affect the efficiency...
