Experiment # 03 Demonstration of a Bend hear on a vane cease Objectives: * To check whether the steel bar has copious ductility to withstand wriggleing without fracture machine exposition: 1. Universal exam machine: A universal proposition testing machine is used to test the tensile accent mark and compressive stress of materials. It is named after the fact that it can perform many another(prenominal) criterion tensile and compression tests on materials, components, and structures. It has the following wholes: * effect social unit: In this unit the specimen is cl antiophthalmic factored and the desired ladle is applied. It incorporate of the following components: * Table * Table cover * tug * Screw drive * Upper and lower cocker lead * 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 co mponents: * 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. freeze Theory: Bending test is often done on samples to check whether they atomic number 18 fictile or brittle. Steel bars behave been divided into assorted categories and have been designated with different numbers.
These duty assignments correspond to the diameter atomic number 18as of the steel bars. For severally group of steel bar there is a token(p renominal) bend tippytoe to which the bar m! ust be stage dance band to be regarded as ductile. If it breaks before attaining that move 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) = assigning/8 The specimen we are using is a surname 8 which means its diameter is 1. Pin: For each designation of the steel...If you want to get a full essay, cabaret it on our website:
