shape. The example of GFRP is shown in figure xx. This material can replace cold rolled steel as purlins or girts. If GRFP is utilized‚ the portal frame section can be design to consume less steel because GFRP is light weight. Since it has a very high strength to weight ratio‚ being light weight‚ GFRP does not make it loose its strength. Regardless‚ this material still possesses less strength compared to steel. This material is also environment and corrosion resistance‚ so when used as purlins or

that can be observed in this zone: they are the Widmanstatten patterns and columnar grains. These patterns are observed to have random directions. The Widmanstatten patterns appear due to large austentite (gamma-Fe) grains being cooled rapidly‚ as steel is a good conductor of heat. The rapid cooling also resulted in the columnar grains. Zone 2: grain growth zone In the grain growth zone‚ it is observed that grains are just starting to form and grow‚ and that there are many open grain boundaries

A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are

And yet‚ these works also help measure just how far the context in which Serra produces and exhibits his sculpture has shifted since the late 1960s. In truth‚ I’ve never liked the torqued steel works that have become Serra’s signature‚ and Inside Out‚ a maze formed by two long‚ wavy metal sheets that occupied most of Gagosian’s 21st Street gallery (this part closed in February)‚ feels like more of the same.

Lecture 3: Structural functionalism Structural functionalism – Radcliffe-Brown Anthropology is a natural science Radcliffe-Brown was one of the main figures of the structural functionalist school of British anthropology. He viewed anthropology as a natural science‚ similar in essence to the physical and biological sciences. The object of natural science was to investigate the structure of the universe. Social phenomena constitute a distinct class of natural phenomena‚ and social structures

What is welding? When did it first come about? How does it work? Welding is a method of creating or repairing metal structures by joining several individual pieces of metals together through various forms of fusion processes. The history of welding dates back to ancient times. The earliest known examples of welding came from the Bronze Age. During the Middle Ages blacksmithing was developed and many items of iron were forged together by hammering. During the 19th century was when welding became to
