CE30160 Lecture Notes - Lecture 5: Standard Deviation, Modulus Guitars, Compression Member
Document Summary
Material types: amorphous, crystalline, cementitous, ceramics, polymers, metals (ferrous & non- ferrous) Understand the time value of money (future cost vs present cost). Be able to apply that to the life cycle cost analysis of a project/material component to aid in making an engineering recommendation. Understand the cost benefit analysis and how that can be applied to aspects of projects that have monetary value and non monetary value. Definitions and some properties you should know how to calculate: Stress-strain know the different between engineering and true stress & strain. Know what stress-strain curves look like for brittle and ductile materials. Coefficient of thermal expansion stresses that may be induced as a result of expansion/contraction in addition to the expansion and contraction of a material. Modulus of elasticity: be able to calculate based on stress and strain. Understand how it affects the strength of a column or any compression member.
