Solve 7.83 assuming that the 300-lb force applied at D is directed upward. PROBLEM 7.83 (a) Draw the shear and bending-moment diagrams for beam AB, (b) determine the magnitude and location of the maximum absolute value of the bending moment.

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
