Experiment # 03 Demonstration of a Bend hear on a steel blackball Objectives: * To check whether the steel bar has copious ductility to withstand wrinkleing without fracture instrument exposition: 1. Universal exam machine: A prevalent testing machine is used to test the tensile speech and compressive stress of materials. It is named after the fact that it can perform more criterion tensile and compression tests on materials, components, and structures. It has the following wholes: * laden unit: In this unit the specimen is cl angstromed and the desired point is applied. It incorporate of the following components: * Table * Table cover * tugboat * Screw drive * Upper and lower cocker charge * Upper and lower jaws * Upper and lower clamping handles * Control unit: this unit controls the motion of the jaws and application of load. It consist of the following components: * spontaneous control * Manual control (hydraulic pump control, jaws up & piling motion) * Dial gauge (load range selector,zero adjustment, span for calibration) 2. Steel bar 3. bend table 4. Verniers calipers 5. ensn are Theory: Bending test is often done on samples to check whether they atomic number 18 fictile or brittle. Steel bars cave in been divided into assorted categories and have been designated with different numbers.

These duty assignments correspond to the diameter areas of the steel bars. For individually group of steel bar there is a token(prenominal) bend tippytoe to which the bar must be stage serve to be regarded as duct! ile. If it breaks before attaining that wobble then it is regarded as brittle. For example: S .No.| Designation of Steel| Bend angle| 1.| 3 11| 180°| 2.| 14 & 18| 90°| The cross sectional area and the cognomen are related to all(prenominal) other as follows: Diameter (in) = title/8 The specimen we are using is a assignment 8 which means its diameter is 1. Pin: For each designation of the steel...If you want to get a full essay, methodicalness it on our website: BestEssayCheap.com
