The work of the external forces in the spring system of the figure is given by W=B*(U1+U2+U3)(2) W=P1*U1+P2米U2+B米U3(3) None of the above statements

16.21 Techniques of Structural Analysis and sig Spring 2003 Unit #1 In this course we are going to focus on energy and variational methods for structural analysis. To understand the overall approach we start by con- trasting it with the alternative vector mechanics approach

earning objectives Understand the importance of project quality management and the role of the project manager in assuring quality Define quality and how it relates to various aspects of information technology projects

Obiectives Understand the systems view of project management Explain the four general phases in the project life cycle Explain the differences among functional, matrix, and project organizational structures

I Atom movement in sol ids mechanical movement thermal vibration (short-range migration) Thermal motion diffusion(long-range migration)

1. There have no two-phases area in diffusion area, every layer is single-phases 2. Phase's interface moves according to parabola law 3. Phase's width

2.1 Introduction 2.2 Micro-organisms as catalysts of organic synthesis 2.3 Enzyme preparations versus whole cell processes 2.4 Scale of production 2.5 Modes of operation of bioprocesses 2.6 Biotechnological processes verses chemical synthetic processes

6. 8 Diffusion Mechani sm Flick's' law in microscopic form 1. One dimensional diffusion. jump frequency period probability of atom jumping to nearest position

Edge dislocation 1. Slip (glide) Dislocation motion vs. atom movement. Direction:l⊥讠 Plane:lb(l× Dislocation motion vs. crystal movement. → crystal movement→(dislocation motion)
