Consider the fuel element of Example 5.11. Initially, the element is at a uniform temperature of 250 C with no heat generation. Suddenly, the element is inserted into the reactor core, causing a uniform volumetric heat generation rate of q . 108 W/m3 . The surfaces are convectively cooled with T 250 C and h 1100 W/m2 K. Using the explicit method with a space increment of 2 mm, determine the temperature distribution 1.5 s after the element is inserted into the core. 5
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
