COURSE DETAILS:

Course Description*

Engineering structures are ubiquitous. From bridges to skyscrapers to pipelines carrying sustainable fuels, these structures are subject to constant loads and stresses in a multitude of harsh operating environments. It is crucial to understand the governing principles in solid mechanics so that infrastructure can be designed to be robust, reliable and resilient, with a high degree of safety and longevity. This course will provide a comprehensive introduction to solid mechanics, including statics, stress, strain, and deformation. Equilibrium conditions, axial loading, torsional loading, pure bending, stresses and deflections in rods and beams are topics that will be discussed. The role of statics and mechanics of materials in setting modern codes and standards for engineering structures will be explored. Hands-on labs will explore the practical aspects of statics and mechanics of materials.
