CE2703 Study Guide - Final Guide: Shear Stress, Shear Force, Compressive Stress
Document Summary
Solid a substance that does not flow perceptibly under moderate stress, has a definite capacity for resisting forces which tend to deform it, and under ordinary conditions retains a definite size and shape. Plastic any of numerous organic synthetic or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments. Liquid a fluid that has no independent shape but has a definite volume and does not expand indefinitely and that is only slightly compressible. Gas a fluid (as air) that has neither independent shape nor volume but tends to expand indefinitely. Fluid having particles that easily move and change their relative position without a separation of the mass and that easily yield to pressure, capable of flowing. Emulsion a system consisting of a liquid dispersed with or without an emulsifier in an immiscible liquid usually in droplets of larger than colloidal size.
