Knowing the preorder and inorder traversals of a binary tree will enable you to uniquely define the tree. The same is true for the postorder and inorder traversals. a. Draw the unique binary tree that has the following preorder and inorder traversals: Preorder: A, B, D, E, C, F, G, H Inorder: E, D, B, A, G, F, H, C b. Draw the unique binary tree that has the following postorder and inorder traversals: Postorder: B, D, F, G, E, C, A Inorder: B, A, D, C, F, E, G

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
