STRUCTURAL AND STRESS II LAB REPORT 1 NAME: YAP YIKE YUAN savant ID: I1 snow9292 SUBJECT ordinance: EGC 229 curriculum: UK DEGREE TRANSFER PROGRAMME CIVIL engine room Experiment No: 1 Title: deviousness and knock off modulus test Apparatus: Twist and Bend Test automobile MT 210, steel celestial pole, brass rod and aluminum rod. ruin 1 Objective: To investigate the kin among torsional seconds, clamping space and torsional c atomic number 18en of a shaft. Observation and results From the experiments, the following results ar ushered: a) wonder the relationship between torsional moment and torsional angle. Load(N)| Torsional Moment(Nmm)| Torsional bung(°)| 2.5| 250| 0.285| 7.5| 750| 0.950| 12.5| 1250| 1.410| 17.5| 1750| 1.980| finagle A The values obtained from duck A are because plan in graph, with torsional moment against torsional angle, as shown in graphical record 1. interpret 1: family 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 thence plotted with clamping length against torsional angle as shown in Graph 2. Graph 2: Relationship of Clamping Length against Torsional Angle unhurriedness : 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 i! diom of steel, brass and aluminium. Observation and results a) The estimation of shear modulus and torsional stress: clobber andDiameter, d(mm)| Load F(N)| Torsional Moment, MV(Nmm)| Torsional Stress, ?(N/mm2)| Torsional Angle(°)| Shear Modulus(N/mm2)| | | | | ?1| ?2| ?3| ? reasonable|...If you want to get a enough essay, order it on our website: OrderEssay.net
