ENGINEERING LABORATORY III (BDA 27101) TOPIC 1: TENSILE TEST 1. INTRODUCTION The tensile experiment is the most common mechanical test that reveals several important mechanical properties‚ such as: modulus of elasticity‚ yield strength‚ ultimate tensile strength‚ ductility‚ and toughness. The material to be tested is formed into a shape suitable for gripping in the testing machine‚ and then pulled at constant rate until it fractures. The tensile instrument elongates the specimen at a constant

Executive summary In this day and age we have so many forms of transport to take us far or near‚ but the safest and fun way to travel is by flying. Even though it is the safest way of transport accidents still happen due to many reasons. The factor this report will be dwelling on is the way weather phenomena affect these accidents. The purpose of this report is to highlight the possible dangers of certain weather phenomena and research ideas to help prevent these accidents from occurring again.

[As you know‚ these laboratory sessions are compulsory course-work. You must attend them. Should you fail to attend either one you will be asked to complete some extra work. This will involve a detailed report and further questions. The simplest strategy is to do the lab.] Notes For the First Year Lecture Course: An Introduction to Fluid Mechanics School of Civil Engineering‚ University of Leeds.

affect an aircraft‚ in this report I will specifically talk about the microburst. Microbursts are powerful downdrafts associated with thunderstorms. We have been able to identify microbursts through many studies regarding wind shear and meteorology research. Wind shear is basically a rapid change in wind velocity and direction that happen because of many factors in weather conditions. Such conditions include frontal activity‚ temperature inversions‚ and thunderstorms amongst other factors.

numerically investigated. To the best of author’s knowledge‚ the effects of slip boundary condition in the presence of dynamic effects of nano particles have not been investigated yet. The results of the present paper show the flow velocity and the surface shear stress on the stretching sheet and also reduced Nusselt number and reduced Sherwood number are strongly influenced by the slip parameter. The objective of the present study is to analyze the development of the slip effects on the boundary layer

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance
