Experiment # 03 Demonstration of a Bend hear on a stain proscribe Objectives: * To check whether the steel bar has copious ductility to withstand change by reversaling without fracture utensil exposition: 1. Universal exam machine: A everyday testing machine is used to test the tensile vernacular and compressive stress of materials. It is named after the fact that it can perform umteen criterion tensile and compression tests on materials, components, and structures. It has the following wholes: * misdirect social unit: In this unit the specimen is cl amped and the desired load is applied. It incorporate of the following components: * Table * Table cover * column * Screw drive * Upper and lower cocker enquiry * 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: * automat ic 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. crepuscule Theory: Bending test is often done on samples to check whether they atomic number 18 fictile or brittle. Steel bars acquit been divided into assorted categories and have been designated with different numbers. These duty assignments correspond to the diameter beas of the steel bars. For individually group of steel bar there is a token(prenominal) bend tippytoe to which the bar must be stage stage set to be regarded as ductile. If it breaks before attaining that list 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 apiece other as follows: Diameter (in) = appellation/! 8 The specimen we are using is a grant 8 which means its diameter is 1. Pin: For each designation of the steel...If you want to get a full essay, stray it on our website: BestEssayCheap.com
