of polymers vary significantly from polymer to polymer as a result of atomic structures and bond strength. The tensile properties of representative samples from the common polymer were tested and evaluated in this experiment. This laboratory experiment is also designed to demonstrate the procedure used for obtaining mechanical properties as modulus of elasticity‚ yield strength‚ ultimate tensile strength (UTS)‚ uniform elongation‚ elongation and reduction in area at rupture. This report is based on

maximum bending stress in the shaft is less than the endurance limit of the shaft material. Hence endurance limit shall be as high as possible for better reliability. Normally endurance limit or fatigue strength is half of tensile strength. Hence if we compare SS 316L & SS 410 tensile strength‚ SS 410 has better endurance limit then SS 316L. Corrosion resistance is property to resist material corrosion. As both SS 410 & SS 316L are Stainless steel‚ both have almost similar corrosion resistivity

Kettlebell Strength Training The Reality Of The Kettlebell. In this introductory article to kettlebell training‚ I’ll be discussing some of the pros and cons of this training tool. I will look at the realistic benefits one can gain from training with it and also some of the limitations involved in it as well as some of the dangers.To begin‚ many people ask me if kettllebell training is effective for gaining muscle mass and strength. To answer this as completely as possible I’ll need to begin

John Moore April 25‚ 2013 | Four Advanced Training Methods As individuals in the exercise world we like to have a lean and sculpted body. Beginner and advanced bodybuilders want to attain the knowledge to increase already known techniques in the strength training arena. There are many ways that one can build their muscles. So we are going to explore four various muscle building techniques and their pros and cons. These are but not limited to techniques such as: Super Sets‚ Forced Reps‚ Pyramid System

Choose 5 different machines and spend 5 or more minutes on each. Or choose 3 machines and hit each for 15 minutes. Mixing things up can make your workouts seem shorter and more interesting. Try this Cardio Medley Workout for ideas. Mix and Match your Strength Training. If you’ve been doing the same old routine for awhile‚ try mixing things up by using different types

Some people think that old persons should not make too much effort or should save their strength and rest because of their age. They think themselves too old to do some physical activities because they think that it is too late to start exercising‚ exercising can put them falling down and they cannot follow physical activities because they are not able to do it. In the contrary this article show how these old people should do exercise because of the benefits for the body‚ the maintenance of health

fatigue life and tensile strength for magnesium alloy were investigated in this study. At least 20 specimens were tested to obtain the scatter data of fatigue limit‚ fatigue life and tensile strength‚ respectively. The probability distributions of fatigue limit‚ fatigue life and tensile strength were evaluated by using Normal distribution and Weibull distribution function. The values of the Weibull modulus‚ m were 159‚ 10‚ 175 for fatigue limit‚ fatigue life and tensile strength‚ respectively. Therefore

totally dependent on other persons in daily life. The vast majority of individuals with RA belong to FC II. Pain‚ stiffness‚ and fatigue generally occur early in the course of RA. Reduction of body function‚ such as range of motion (ROM)‚ muscle strength‚ and aerobic capacity‚ may follow. As previously summarized by van den Ende et al (5)‚ 50% of patients with RA displayed decreased hand ROM at their first rheumatology visit. Two years later‚ reduced ROM was found in large joints; the decreased

Properties of paper Physical Properties Basis Weight or Grammage The basis weight‚ substance or grammage is obviously most fundamental property of paper and paperboard. The Basis weight of paper is the weight per unit area. This can be expressed as the weight in grams per square meter (GSM or g/M2)‚ pounds per 1000 sq. ft. or weight in Kgs or pounds per ream (500 sheets) of a specific size. Paper is sold by weight but the buyer is interested in area of paper. The basis weight is what

mechanical stre ngth of cement by applying Compressive and Tensile tests on Cement-Sand mortar. Standards: ¾ Compressive strength of cement using mortar cubes: B.S.12 – Part 2 ASTM : C 109 ¾ Tensile strength of mortar using briquettes: B.S.12 – Part 2 ASTM : C 109 General Discussion: In these tests (Compressive and Tensile tests) we measured the mechanical strength of the hardened cement. These tests are done on cement – sand mortar and not on the hardened cement itself‚ the r eason
