This course will be helpful for Mechanical, Production, and Civil Engineering Students. It will give the knowledge of simple stresses, strain along with the numerical analysis. The purpose of course is to provide the students with solid foundations in the basic concepts of stress strain for homogenous and isotropic material. The main objective of the course is to teach the students design and analysis of members subjected to compressive, tensile stress. This course also teaches the student to analyze the combined loading conditions . This course will teach the students about the units used in stress. This course also addresses the stress-strain diagram for ductile as welll as brittle material. In this course the numericals to find out the stress and strain are covered. Along with this the concept of factor of safety is covered. In this course, numerical on different sections of the rod is covered. It also covers the concept of Engineering Stress-Strain and True stress strain curve. This course will be helpful for Mechanical, Production, Civil Engineering Students. It is a beginner-level course. This course will covers the concept of hookes law, modulus of elasticity. It also gives brief idea about the shear strain, shear stress and modulus of rigidity.
