PPT-MECHANICAL PROPERTIES OF SOLIDS

Mohamed Sherif K HSST Physics GHSS Athavanad Deforming Force amp Restoring Force A force which changes the shape and size of a body is called deforming force When a deforming force is applied the body may get deformed Then the force developed inside the body which try to bring the body back to its original shape and size is called restoring force. Module 1. Session Topics. Surfaces and Solids of Revolution. Degree of Revolution. Hollow Objects. Visualizing Revolution. Surfaces and Solids of Revolution. Surfaces and Solids of Revolution are formed when a 2-D shape is revolved about an axis. -Describe . these objects-. What are some things that you notice?. Have you ever seen anything like these? Where?. What do they remind you of?. How would you describe these objects?. How can we describe these using geometric terms?. Technical objects are made from materials.. Materials can be divided into three categories.. Raw Materials. Materials . Equipment. M. aterials. Raw Materials:. substances that need to be transformed before they can be used to make a technological object.. ● . Phases and Phase Diagrams. ● Liquids and Liquid Properties. ● Intermolecular Forces. ● Heating Curves. ● Introduction to Solids. ● Cubic Packing Arrangements. ● Closest-Packed Structures. By the end of the lesson you should know. The names of the states of matter. That matter is made of particles. How the particles are arranged in solids liquids . and gases. The names of the changes of state. All . faces, all edges, all corners, are the . same.. They are . composed . of . regular 2D polygons:. There were infinitely many 2D n-. gons. !. How many of these regular 3D solids are there?. Making a Corner for a Platonic . The quick review. Properties shared by All Matter. Mass. Volume. Density. Know what these are!. Matter in Different Materials Can Have Different Properties. characteristics it possesses by itself . (in and of itself). SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . Beaker. USE:. Holds solids or liquids. Poor accuracy- only estimates volume. Hot Hands. USE:. Use to hold beakers when warm. Should not be used when liquid is boiling. Graduated Cylinder. USE:. Measure volumes of liquids. Geometry. Chapter 12. This Slideshow was developed to accompany the textbook. Larson Geometry. By Larson. , R., Boswell, L., . Kanold. , T. D., & Stiff, L. . 2011 . Holt . McDougal. Some examples and diagrams are taken from the textbook.. Lecture Presentation. Classifying Solids Based on Bonds. Metallic solids. are held together by a “sea” of collectively shared electrons.. Ionic solids. are sets of cations and anions mutually attracted to one another.. Period Motion. Any . motion that . repeats. at regular time intervals. Frequency. Number . of . complete cycles . in a given . time. Frequency . is measured in . Hertz (Hz). Properties of Mechanical Waves. 720.82 83.82 Add water, mix Water 98.31 11.82 (to maintain 30% T.S.) Add Bayhydur with moderate agitation, mix for 1 - 2 minutes.
