Material

would think people would start to be more accepting of emotions, facts, and ideas. Today, we live in a society where people are trying to remove or confine reading materials to enhance safety, security, and to avoid politics and corruption. In my opinion, I would not want to ban reading materials. If someone were to ban reading materials, I would address the concern by simply telling them my thoughts on the matter by either speaking face to face or creating a blog post with the ideas of banning…

The purpose of this lab is to ascertain the hardness of two different materials. One material is aluminum the other will be determined through testing. Hardness is defined as a material’s ability to resist plastic deformation by indentation. Harder objects are more likely to resist deformation. The results of a hardness test will be important for engineers to determine what material will work best for a project. The material will need to hold up to any stress put on it and be able to work…

the drain. It costs a fraction of a penny for tap water when millions are waste to make bottled water. More than half of all bottled water comes from tap water. One of the worst problems for the economy is pollution and pollution made by plastic materials. The environment is in desperate need of recycling if the population persists on producing bottled…

As you consume bottled water, you are also taking the risk to get cancer and various reproductive damages. Human body need water, it is our biological needs. However, people choose to drink bottled water is just for them to meet their secondary needs. If you could choose between bottled water and drink water fresh out from the tap, I believe you would go for bottled water. No doubt that our body needs water to survive. In US, most of the people have the access to tap water, but there is a large…

same load. As a result the graft part is wider than the vessel itself. On the other hand, silicon rubber is displaced less than the vessel and axiomatically narrower than the vessel itself. The reason and main cause of this difference between two materials is that, the stiffness of polyurethane is lower than that of the vessel and on the other side silicone rubber has a higher stiffness value. This matter can affect hemodynamic parameters as narrowing the section can increase the velocity and…

Briefly describe 2 developmentally appropriate materials or activities you would add to the environment to address skills for this age group. 1. Infants need a variety of toys that they can manipulate. This includes soft rattles, stuffed animals, and plastic stacking rings. This will promote development in multiple domains, while supporting their growing spatial awareness and attachments. 2. A developmentally appropriate activity to do with 0-1-year old’s, is to sing to them. Music offers…

replacing bone and mimicking their structure for, various applications. When looking at biological materials, to determine their effectiveness as a scaffold or sufficient structure for various other uses, often they are tested for their resistance to fracture. This is referred to as fracture propagation. Bamboo Bamboo is well known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it…

The aim of the Stress Concentration Experiment was to observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress. With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test…

A Description of the Leatherman Raptor Shear INTRODUCTION: The Leatherman Raptor shear is a compact, multi-tool, that was designed for medical and emergency professionals to have an all-in-one tool to use in survival situations. These beneficial shears contain several useful tools, such as an oxygen tank wrench, auto glass breaker, belt strap cutter, and ring cutter. DESIGN: The Leatherman Raptor shear folds into a compact size of 5 inches in length and comes with a convenient belt clip for…

MANUFACTURING COSTS: Functional Elements: The baby stroller is mainly composed of three materials: Nylon (woven, as fabric) Plastic (injection molded, for plastic parts) Steel (tubing, for frame) Fasteners are included in the assembly of different components of the strollers. The stroller would have to be manufactured on an assembly line. The fabric weaving and seat making, the plastic molding and the frame can simultaneously be manufactured in their respective work areas. Following are…
