    of materials by using a tension test. The properties that were determined was Young’s Modulus, ultimate tensile strength, and yield strength. Three aluminum alloys were tested. The first was the AA 2024 , which is high strength used in aerospace applications. The second specimen was AA 5052, which had low strength, but high ductility. The last specimen used was AA 6061, which has moderate strength and is highly resistant to corrosion. Procedure: To test each specimen, a tension test machine was

The mechanical properties of concrete determined in the laboratory include compression strength, splitting tensile strength and flexural tensile strength. The influence of partial replacement of fine aggregates by copper slag on the compressive strength, split tensile strength on cylinders and flexural strength of prisms has been evaluated. The test results showed that there is a possibility of use of copper slag as fine aggregate in

    1.Introduction Stainless steels are engineering materials and it are a complex group of iron based alloys containing at least10.5% chromium and a maximum of 1.2 % carbon. In order to define the stainless steel it can be said that the base alloy for this material is iron which contains a minimum of %11 Chromium (Cr) [1]. The European Standard EN10088 (EN2005) defines stainless steels as iron based alloys containing at least10.5% chromium and a maximum of 1.2% carbon. The main factor for the corrosion

Borosilicate glass is made to withstand thermal shock better than most other glass through a combination of reduced expansion coefficient and greater strength, though fused quartz outperforms it in both these respects. Some glass-ceramic materials include a controlled proportion of material with a negative expansion coefficient, so that the overall coefficient can be reduced to almost exactly zero over

    I. Introduction The purpose of this lab was to observe and record the bending stress and elastic properties multiple materials. A three-point bend is when a force is applied to the center of an object while it is supported on each side. This experiment was performed to record each material's flexural behavior so applications can be made with appropriate materials. The objective was to calculate the elastic modulus for each material tested. II. Methodology To start the lab, one measures and

    Ductile/brittle Fracture Ductile materials are materials which displays large numbers of plastic deformation, while brittle materials show little or no plastic deformation before fracture. The diagram is the a tensile stress-strain curve, which represents the degree of plastic deformation exhibited by both brittle and ductile materials before fracture. Crack initiation and propagation are vital to fracture. The manner in which the crack propagates through the material gives great insight into the

    Trusses are crafted from a straight and slender pieces of material manufactured then connected at various joints to form a triangular shape. The common purpose of truss is to construct a large structure with the shape and design of truss adding strength and weather resistance to the overall structure(Šimi & Ilijaš, 2012). Truss can be designed as planar trusses, which are a two dimensional shape that commonly used in roofs and floors while space trusses are three dimensional shapes. Multiple trusses

The advantages would be the vacuum bagging finished part possesses a better strength and the part is lighter. The process is not difficult and very easy to switch to, and also the materials for basic parts are affordable and can be accessed easily.

The water melon is a fairly complex structure with a tough outer skin over a thick flexible rind covering a pulpy middle that has very little strength. Much of the drama in the video comes from the dramatic catastrophic failure of the outer layers leaving the weak interior material to be crushed and squirted about by the rapidly converging rubber

    • 5 Pages

    History of asbestos. There are four main types of asbestos; Amosite (brown fibers), Anthophyllite (gray fibers), white Christie, and blue Crocidolite. Chrysotile has curly fibers while the other three have rod like fibers. These fibers fragment into dust quite readily and waft into the air. They can adhere to skin or clothing and are easily swallowed or inhaled. Half a century ago, asbestos was hailed by many as a miracle product. They said nearly anything could be made from this mineral. It as
