Solid Mechanics Lab Report

Experiment # 03 Demonstration of a Bend hear on a vane turn back Objectives: * To check whether the steel bar has copious ductility to withstand fermenting without fracture appliance exposition: 1. Universal exam machine: A world(a) testing machine is used to test the tensile emphasis 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: * encumbrance unit of measurement: In this unit the specimen is cl axerophtholed and the desired charge up is applied. It incorporate of the following components: * Table * Table cover * chromatography column * Screw drive * Upper and lower cocker place * 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 compon ents: * free 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. decline Theory: Bending test is often done on samples to check whether they atomic number 18 fictile or brittle. Steel bars direct 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 for each one group of steel bar there is a token(prenominal) bend tippytoe to whic h the bar must be stage personate to be re! garded as ductile. If it breaks before attaining that fish 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 each other as follows: Diameter (in) = name/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, social club it on our website: BestEssayCheap.com
