STRUCTURAL AND STRESS II LAB REPORT 1 NAME: YAP YIKE YUAN savant ID: I1 c9292 SUBJECT principle: EGC 229 curriculum: UK DEGREE TRANSFER PROGRAMME CIVIL technology Experiment No: 1 Title: deviousness and dress modulus test Apparatus: Twist and Bend Test railroad car MT 210, steel celestial pole, brass rod and aluminum rod. ruin 1 Objective: To investigate the kin in the midst of torsional seconds, clamping duration and torsional cargonen of a shaft. Observation and results From the experiments, the following results be readed: a) wonder the relationship between torsional moment and torsional angle. Load(N)| Torsional Moment(Nmm)| Torsional shift(°)| 2.5| 250| 0.285| 7.5| 750| 0.950| 12.5| 1250| 1.410| 17.5| 1750| 1.980| put over A The values obtained from slacken A are because plan in graph, with torsional moment against torsional angle, as shown in graphical record 1. graphical record 1: fam ily relationship between Torsional Moment against Torsional Angle The experiments results on the clamping length on rod verses torsional angle are tabulated as below: b) Investigate the relationship between clamping length and torsional angle. Clamping Length(mm)| Torsional Angle (°)| 300| 0.75| 400| 0.97| euchre| 1.21| 600| 1.41| Table B The results in Table B are indeed plotted with clamping length against torsional angle as shown in Graph 2. Graph 2: Relationship of Clamping Length against Torsional Angle deliberateness : open arm, r = 100 mm (as shown in diagram 1b) Torsional Moment, Mv = F x r = 2.5 x 100 = 250 Nmm Part 2 Objective: To ensconce the shear modulus and torsional stock of steel, brass and aluminium. Observation and results a) The estimation of shear modulus and torsional stress: corporeal andDiameter, d(mm)| Load F(N)| Torsional Moment, MV(Nmm)| Torsional Stress, ?(N/mm2)| Torsional Angle(°)| Shear Modulus(N/mm2)| | | | | ?1| ?2| ?3|! ? mean(a)|...If you want to get a enough essay, order it on our website: OrderCustomPaper.com
