Materials that better suit a specified use. This lab tested two materials mild steel and cast iron. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated properties included true fracture strength‚ percent reduction of area‚ and percent elongation. These material properties were used to define the material as brittle or ductile. INTRODUCTION: Mechanical testing plays an important role

Kevlar ’s structure consists of relatively rigid molecules‚ which tend to form sheet-like structures that have similarities to silk proteins. Kevlar can be used by itself or as part as o composite material to give added strength. It is best known for its use in bullet proof vests and knife proof body armour. It is also used for reinforcement in car tires‚ car brakes‚ strings of archery bows‚ and also in car‚ boat and aircraft bodies. Kevlar is used in the aircraft Apache

contrast to the damaged condition of a number of RC frames and dual systems (i.e.‚ RC frames with shear wall configurations). Thus the tunnel-form system has become a primary construction technique in many seismically active regions. In this paper‚ the strengths and weaknesses of tunnel-form buildings are addressed in terms of design considerations and construction applications. The impacts of shear wall reinforcement ratio and its detailing on system ductility‚ loadcarrying capacity and failure mechanism

improvements‚ I have improved the strength of my upper body‚ for example arm and trunk strength. b) In order to improve my muscular fitness level‚ I need to devote time to work on each part of my body. Taking into consideration the rest time between workouts‚ I need to train each muscle group of my body. For example‚ my Upper body will be trained 2 times a week‚ and Lower body on other two days of the week. As for intensity‚ since I am willing to improve my muscular strength‚ I should perform 1 to 3 sets

My Final Speech - Why you should live a healthier lifestyle. Everything below this is my rough outline of my final speech. The point of this post is that I want to follow through with what I’m going to say. I don’t want to sound like a hypocrite and say “oh you all should do this” when I can’t even do it myself. It’s like lying to everyone‚ I shouldn’t say things I can’t do myself. “Don’t make promises you can’t keep.” So from now until the end of the quarter (or even better‚ the rest of my life)

Abstract This experiment will explain what the Rockwell hardening test is and why it is used‚ how the experiment was conducted‚ data that was found‚ and the importance of testing the hardness of materials. This experiment explains and proves how the hardness of materials can be increased by alloying and heat treating. Intro – Rockwell Hardness Testing Soft and hard qualities exist in materials. In materials‚ hardness measures the ability of a material to resist scratching‚ indentation‚ or penetration
