used to test the tensile stress and compressive strength of materials. It is named after the fact that it can perform many standard tensile and compression tests on materials‚ components‚ and structures. The range of the UTM available at the laboratory is 8 to 36 mm and has the capacity of 5 to 100 kN. D. TENSILE TESTING MACHINE The tensile testing machine is a specialized machine designed for tensile testing This measures how strong it is (tensile strength) how stretchy it is (elongation)

Predicting the compressive and tensile strength of rocks from indentation hardness index by S. Kahraman*‚ M. Fener†‚ and E. Kozman‡ Synopsis The prediction of rock properties from indirect testing methods is important‚ particularly for preliminary investigations since indirect tests are easier and cheaper than the direct tests. In this study‚ we investigate the predictability of the uniaxial compressive strength (UCS ) and Brazilian tensile strength (BTS ) of rocks from the indentation hardness

Properties that are directly measured via a tensile test are ultimate tensile strength‚ maximum elongation and reduction in area. From these measurements the following properties can also be determined: young’s modulus‚ poison ratio‚ yield strength‚ and strain hardening characteristics. 3.The tension tester A machine which applies a tensile force (a force applied in opposite directions) to the specimen‚ and

Materials * Helical spring * support * rods * weight hanger * slotted masses * vertical scale * stopwatch. Procedure Part I: Determination of k from Hooke’s Law 1. Suspend the spring from its support. 2. Hook the weight hanger from the bottom loop of the spring and determine the vertical scale reading of the bottom of the weight hanger. 3. Record this as the equilibrium position of the system. 4. Add 5 g to the weight hanger and again record the actual

High strength to weight ratio‚ environmental resistance‚ high stiffness and good wear resistance are the characteristics that encourages more research to develop their applications with further improvement in the properties. Ceramic particles such as SiC‚ Al2O3‚ B4C‚ TiC and TiB2 are the widely used materials for reinforcement of aluminium [1]. Boron carbide (B4C) is one of the most promising ceramic materials due to its high strength‚ low density (2.52 g/cm3)‚ high hardness

TESTING AND SPECIFICATION OF DRYMIX MORTAR IN SINGAPORE ABSTRACT Singapore is a small island country‚ but has won renown as uncorrupted government and high quality products. Independent testing and inspection played a very important role for this achievement. The Housing and Development Board (HDB) is the sole public authority in Singapore and was set up as a statutory on 1 February 1960. Within 45 years‚ it built more than 700‚000 flats housing approximately 86% of the population. Every

Chair Biological Systems Engineering (ABSTRACT) Metal-plate-connected (MPC) splice joints were tested in combined tension and bending to generate data that were used in the development of a design procedure for determining the steel net-section strength of bottom chord splice joints of MPC wood trusses. Several common wood truss splice joint configurations were tested at varying levels of combined tension and bending loading. The joint configurations were 2x4 lumber with 20-gauge truss plates‚ 2x6
