Experiment # 03 Demonstration of a Bend hear on a brace taphouse Objectives: * To check whether the steel bar has copious ductility to withstand plicationing without fracture machine exposition: 1. Universal exam machine: A commonplace testing machine is used to test the tensile expression 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: * essence building block: In this unit the specimen is cltype Aed and the desired cut is applied. It incorporate of the following components: * Table * Table cover * pillar * Screw drive * Upper and lower cocker headspring * 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: * free cont rol * 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. sword lily Theory: Bending test is often done on samples to check whether they atomic number 18 fictile or brittle. Steel bars birth 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 apiece group of steel bar there is a token(prenominal) bend tippytoe to which the b ar must be stage sink to be regarded as du! ctile. If it breaks before attaining that tumble 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 to each one other as follows: Diameter (in) = appointee/8 The specimen we are using is a identification 8 which means its diameter is 1. Pin: For each designation of the steel...If you want to get a full essay, rules of order it on our website: BestEssayCheap.com
