In the 70's, the Republic of the Philippines was suffering under the midst of then- President Ferdinand Marcos' reign as ruler. It was in September 21st, 1972, that he chained close whatever inkling of democracy the Filipinos had by declaring Martial Law. Unfortunately, it was a rule of a a twisted sort: the nation would be under the rule of the Armed Forces, but contrary to its definition, Marcos' Martial Law kept himself in power. Dekada '70 (Translated into English, the 70's decade) is a bittersweet tale of love in the face of hate, hope in the face oppression, and new life in the midst of death. It is a novel of a mother, her examination of her oft-unappreciated role in modern society, and how she struggles to find for herself a sense of purpose and identity while suffering through the very pit of the nation's disintegration. It is a novel of a mother and her family, how society around her affects her family. It is a tale of she becomes torn between the letter of the law or her responsibility as a mother. Dekada '70 tells of how under hate, greed and corruption, one normal person transcends beyond right and wrong: instead learns that it is freedom that entails survival. Set in the 70's, urban Metro Manila, Amanda Bartolome is a middle-class mother of five young men. Amanda acts as a supposed symbolism of detachment. First of all, she was a mother, a housewife; such were not considered integral parts of society during those times. She was not the breadwinner; she did not experience the foremost effects of the decline of the Philippines economy back then. She was a member of the middle class; her family did not take money, like the rich, nor did her family suffer the worst of the financial crises, like the poor. The lives of Amanda's children each went in different directions in the story, and each varied. Her eldest son was Jules. Jules grew up normally, similar to every other ideal family. His upbringing was that of what ideally conformed to normal.

Assembly Automation and Product Design - Essay Example

The electrical function refers to the plugs ability to properly conduct current from the socket to the electrical device in a safe and proper manner. The mechanical function refers to the sockets ability to withstand all the forces required for safe installation of the plug into the socket. The mechanical function also includes the proper design of the plug so as to safely clip into the socket and be safely held and removed from the socket. Aesthetic function refers to the ability of the socket to have appealing features to the customer. Ergonomic function refers to the sockets ability to withstand fatigue due to continual use.2
The 13A pin is made of the following components. Conductors are the three pins; they are made of brass. Fuse element made of copper. Fuse clip made of copper, cable wires made of copper and fuse ends made of copper. The insulators are the plug body and base made of plastic. The cord clip made of nylon, Cable sheath made of PVC (polyvinylchloride) wire sheath and pin sheath made of PVC. Fuse body made of alumina. The pin has screws firmly holding together all the parts. The cord grip screw is made of steel, the major plug screw is made of steel and the pin screw is made of steel or brass.3
In the process of material selection, the engineer should consider the materials are the best conductors and those that are the best insulators. The engineer should consider the price and the ease of molding and access the materials. Polymers can be shaped into the desired shape of the plug through molding. This can be easily done for mass production. Wood can only be machined; this method is ineffective for mass production. Thermoplastics have various options for mass production such as welding, use of adhesives and molding. Therefore, even though wood provides the cheapest source of raw materials, it is difficult to use it in mass production.
The plug body should be strong and stiff so as to hold the pins safely. Through a material selection process an engineer is able to select the most suitable polymer to use.Â
