- Apportionment, Allocation, and Absorption of Overhead

Total overhead=€650000, Thus overhead as percentage of Direct material cost=650000/3430000*100=18.95%.
Thus overhead to be absorbed to Econo bikes at 18.95% of €2150000=€407425, and to Luxi 18.95% of €1280000=€242575
**Under the blanket overhead absorption rate as was the practice, the €650000 overhead absorbed between Econo and Luxi was 2000/3000*650000=€433333 and 1/3*€650000=€216667
1. After all the service department costs are apportioned to the production departments, the next step is to spread the factory overhead to the different products or job produced. This is termed as overhead absorption Continue reading...

Material Inequality and Political Theory

Defining inequality and determining factors to assume equality and justice remains to be a vague concept as factors like social class, talent, and needs would often influence how people define these terms. According to Fleischacker (2005), adding to the confusion of defining inequality and means to attain 'just distribution' of goods, services, and rights are several definitions and theories established to try and attain 'just distribution'. With the presence of several theories and definitions to attempt explaining how just distribution can be done, concerns on how it would impact society is raised since political theories vary in concentration and Continue reading...

Abstract
Material selection is an important stage in engineering design. Engineers use various materials with different mechanical properties in building of structures. These mechanical properties include; tensile strength, yield strength, proof stress, Young's modulus, shears modulus of rigidity and ductility amongst others. Material selection increases the performance as well as durability of the engineering component. The expected life, cost, nature of loading and working environment are some of the factors that assist engineers to select materials for particular application. Therefore, engineers and designers must be able to determine the properties of these materials before they use them. Engineers use Continue reading...

Question One

It is essential to understand the four classes of materials; this is because it makes us have a clear understanding of the properties that specific materials should exhibit. This plays an important role whenever there is a need to select materials for use in applications. (Ashby, Hugh and Cebon, 2007). This is due to the fact that for every application there are specific properties required, there is always a need to select that material that has exactly the needed property. Hence, the understanding of such properties ensures that the right material is chosen for the correct application. The four Continue reading...

It is a fundamental fact that to be able to begin to understand how society works, we must first garner an appreciation for the individual self and the role that they play within the bigger picture. As human beings, we are socialised into behaving within the sets of norms and values which society and culture place upon us. However, these values are changeable according to specific cultures and societies; paving the way for sub-cultures to arise. When discussing our understanding of society, we are able to assess it from a material viewpoint with the emphasis being on means production Continue reading...

Abstract

Microscopic analysis of materials is generally complex; hence engineers always look for alternative methods of analysis, by appropriate modelling. In specific, studying the damage of materials is important in almost every discipline of science/engineering/technology. Material damage includes the beginning, advancement and fracture of materials. The most important tool so far, used to analyze this damage, is called damage mechanics which relies heavily on continuum mechanics. It encompasses useful theories for the representation, modelling, and analysis of material damage. Broadly speaking, damage mechanics utilizes state variables to show the effects of damage. For instance, the variations in stiffness, and the Continue reading...

Introduction

Rationalism is the major developed concept during the time of John Locke. His goal in his works is to build a more sophisticated foundation for information and science. The method he proposed is to evaluate the scope, limitation and reliability of the knowledge of humans and to differentiate it to the irrational concepts and ideas. He started to investigate the ability of the human mind by analysing the origin of our ideas. Locke believed that in order to understand the human mind, one should trace the origin of the idea from the individual’s experience (Kaijo, np).
John Locke’ Continue reading...

Abstract

The experiment is aimed at constructing a step-up transformer. This is due to the type of materials being used and the number of rolls that the wire is rolled on the U-shaped material. This can easily be related to the alternating current that is tapped from one source to the other. This current can easily be measured in respect to the size of the voltage that is alternated in between the primary transformer and that of the secondary transformer. The number of coils in the primary material is two; the other secondary coil has four coils. The material used Continue reading...

1. Introduction to the Technique
Magnification and high resolution imaging are very important in materials science, especially at present when nanotechnology materials are being created. Magnification and high resolution imaging can help in the characterization, identification, and confirmation of the existence of the desired material. Magnification and high resolution imaging become problems when the size of the assessed material becomes too small; such as, they are beyond the micrometer scale. Ordinary techniques in microscopy such as light microscopy where in a traditional light microscope is used could not suffice. Fortunately, in 1931, two scientists named Ernst Ruska and Mx Continue reading...

Introduction

The above quote alludes to the pliability and the malleability of plastic. Plastic is defined by the online version of the Merriam-Webster Dictionary as a synthetic material which is comprised of a variety of organic polymers which can be moulded into a shape while soft, and then set into a rigid, yet slightly flexible form. Glass fibre reinforced plastic (GFRP) is plastic which has been reinforced or strengthened by the use of glass fibres. This composite material has been used in the construction of large-scale items such as luxury boats, missiles, and tanks, and small-scale items, such as tubs, Continue reading...

Methods of Heat Transfer

Conduction
The first method through which heat is transferred from one object to another is conduction. Conduction occurs in liquids and solids through transfer of kinetic energy present in one particle to the immediate particle(s) in its surrounding. By considering the bonds existing between atoms and molecules in solids as elastic links, the vibration of one particle due to increase energy level caused by heat, the next in its line vibrate too. This process is replicated in adjacent particles thereby allowing transfer of thermal energy from a body with a higher temperature as compared to the one with Continue reading...

Meissner effect is one of the remarkable properties of superconductors. Most superconductors are metals and metal alloys. However, some non-metals also exhibit superconductive properties hence they are regarded as superconductors. A superconductor refers to a material that can transfer electric current with zero resistance. This implies that when electric current is passed through a superconductor at a temperature below the critical temperature value (Tc), no energy is lost in any form: sound, heat, or light. It is important to point out that superconductivity of a material can only be observed at temperature below the critical temperature (Tc). Critical temperature Continue reading...

Introduction

Material Requirements Planning (MRP) and Kanban control systems are one of the most prominent production planning and inventory control systems of today. These systems are the most popular implementations of push and pull strategies respectively. Speaking of MRP, it is a material control system that tries to maintain adequate inventory levels to ensure that the required materials are available, when needed. MRP is used where there are multiple items with complex bills of materials. It is not suited for continuous processes that are tightly linked.

The major objective of an MRP system is to simultaneously:

- Ensure the material availability, components, and products for customer delivery and planned production.

The policy and procedure are enacted to ensure that the constitutional rights of stakeholders are not infringed upon when these individuals are exposed to a particular criminal justice process. Unfortunately, there arises some situations in the course of disseminating justice where some actions cause massive legal disagreements. An individual who has been subjected to a particular process may claim that the process was unconstitutional or that his Continue reading...

Introduction

Tensile testing is usually conducted to select a material for its application, quality control, and to forecast how the material is likely to react on deployment of different types of forces. The properties evaluated through the tensile test include the ultimate tensile strength, the maximum elongation, X-area reduction and so forth. These evaluations facilitate determination of such properties as Young’s Modulus, yield strength, Poisson’s ratio, and the characteristics of strain hardening [1. 2]. Tensile testing on glass fibre is, thus, performed to determine the quality of the material it contains, and to ascertain its suitability for various Continue reading...

When designing various projects for a client, an engineer is concerned with different aspects of the design. For instance, the aesthetic value of the design is very important to the engineer. Other factors that concern the engineer are the durability of the product and the cost effectiveness in both the design and production processes. However, and without belittling the importance of these factors, safety is ultimately the major concern of the engineer. Safety as a factor is incorporated into all designs, for both the client and the environment (including other people who might not necessarily use the product but Continue reading...

Sustainability, as an important aspect of packaging, is increasingly gaining importance. This is fueled material advances, consumer demand and legislation. The argument that paper-based packaging is the best alternative is not only valid but also necessary. Unlike other packaging material, paper-based packaging uses renewable materials; trees. Unlike other products used for packaging, paper based products are the most recoverable. As such, they can be recycled which enhances the sustainability of using paper-based packaging material.
Throughout the life cycle of paper-based packaging products, they are responsible in that even when they are not recovered for recycling, they are Continue reading...

Abstract

Censorship has been a debatable issue for decades with critics viewing it as an infringement on the rights that have been enshrined in many constitutions of many countries; this is the main reason why the notion of censorship in any sector is met with extreme resistance; however, it is a part of history that those holding positions of power often use this idea to suppress what they feel are ideas that might lead to opposition or other fundamental ideas that might threaten their hold over the people; when it comes to literature it is important to consider the effect Continue reading...
