A cylindrical specimen of cold-worked steel has a Brinell hardness of 240. (a) Estimate its ductility in percent elongation. (b) If the specimen remained cylindrical during deformation and its original radius was 10 mm (0.40 in.), determine its radius after deformation.
Introduction (Part 1) What is mechanics The science that describes and predicts the conditions of rest or motion of bodies under the action of forces. What happens to this body o Does it move (Dynamic) o Does it stay still (Static) o Does it deform/ deflect Mechanics is Comprised of Multiple Topics Rigid bodies o Statics o Dynamics Deformable bodies o Mechanics of materials Fluids o Incompressible o Compressible We Will Focus on Rigid Bodies Statics deals with bodies at rest. Dynamics deals with bodies in motion. Mechanics is the Foundation for Mechanical Engineering. Introduction (Part 2) Fundamental Concepts and Pri
