equation: Where: Strain is commonly referred to as either tension or compression depending on the direction of the force applied to the sample. Tensile strain generally refers to elongation of a material as a result of a tensile test. Compressive strain refers to the compressing‚ shortening of a material. In this particular laboratory‚ tensile strain is to be measured through the application of an Instron and extensometer. In this case‚ the extensometer is mounted to the different samples

preventor which will seal off the annulus around the cable and if required cut the wireline 1.1 Wireline Conventional wireline or “slick wireline” as it is frequently referred to‚ utilises a single strand high tensile wire. The wire is normally made from high tensile steel. Minimum diameter of cable to be used‚ which is desirable for the following reasons:- (1) It reduces the total weight of the wireline itself. (2) It is more pliable and can be bent over smaller diameter sheaves

Malaysia‚ PUSPATI Triga Reactor (RTP). It was first used in 1982. Like other Triga reactor‚ it is used only for research and development‚ training and education. The first location we were taken was a polymer lab. At there‚ we learn about sago starch‚ tensile‚ impact and such more. Sago starch‚ an important agricultural commodity of Malaysia‚ can be radiation modified to improve its functionality‚ diversify its applications and increase value added sago products. In this study‚ modification is achieved

ELASTIC DEFORMATION AND POISSON’S RATIO E 45 – Materials‚ Friday 8:00 am September 21‚ 2012 Due: October 19‚ 2012 Abstract A tensile test was performed on a 4140 steel sample and the axial and transverse strains were measured. Data points were collected at incremental loads and graphed to determine the elastic modulus (30.4 x 106). Poisson’s ratio was also calculated from the dataset and determined to be 0.29. These experimental values agree closely (within
