Problem 11-78

The beam is subjected to the triangular distributed load with a maximum intensity of w0 = 300 lb/ft. If the allowable bending stress is u allow = 1.40 ksi, determine the required dimension b of its cross section to the nearest l in. Assume the support at A is a pin and B is a roller.

Step-by-Step Solution:
Step 1 of 3

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 Principles  Mechanics  Space  Force  Time  Mass  Force  Point of application  Magnitude  Direction Six Fundamental Principles of Mechanics  The parallelogram law for addition of forces  The principle of transmissibility  Newton's first law of motion  Newton's second law of motion  Newton's third law of motion  Newton's law of gravitation System of Units and Converting Between Two Systems of Units  Always use matching units when solving a problem.  Always be sure that the final answer has the appropriate units.  If the units do not match, convert them. Method of Solving Problems  Strategy: Read and fully understand a problem before beginning to solve it.  Identify all given values and desired unknowns.  Thin
