INDIVIDUAL FINAL EXAM SPECIALISATION COURSE OPERATIONS AND SUPPLY CHAINS Read this carefully This exam is a closed book exam: you are not allowed to have books‚ articles‚ notes etc. on your desk. Please take care of your handwriting. You need to be very specific about which question you are answering - it is noticed here that often one question exists of several sub questions. Please explain all your answers and write down your name and student number on each sheet

3.4 Thermal Effect Shear strain In general‚ increase in temperature causes the atoms to vibrate more and makes average atomic spacing greater. Macroscopically‚ this will lead to dimension increase in solid: T + T +V T – T – V In an isotropic material‚ temperature change only introduces variation of direct (normal) strain. In other words‚ thermal deformation does not cause shear strain. where T0 is a reference temperature and = coefficient of thermal expansion (C)-1 Hooke’s

Solid Mechanics Lab Report Measurement of Young’s Modulus Sherin Joseph 00549618 Measurement of Young’s Modulus of Aluminium using Cantilever loading Abstract The Young’s modulus of Aluminium was calculated using the measurements of the cantilever deflections. A beam of aluminium was clamped on one end and the other end was loaded with different weights‚ ranging from 1 to 15N. The deflection was then measured using a dial gauge. The slope of a load (abscissa) vs. deflection (ordinate)

University of Manchester University of Manchester NISHANT AGARWAL The report primarily discusses results obtained from the conducted experiments and includes computed data from the Kingston computer program. The value of the plastic moment capacity of each experiment was obtained; Obtained value was used to find the yield strength of the structures and compare them to typical values for mild steel. The important data is summarized in a table; followed by a list of important formulae. All
