Bending Stress in Beams - Problem 7 | Stresses in Beams | Strength of Materials | Solid Mechanics

Question: A rectangular beam 300 mm deep is simply supported over a span of 4 m. Determine the uniformly distributed load per metre that the beam may carry if the bending stress must not exceed 120 N/mm². Take moment of inertia I = 8 × 10⁶ mm⁴. In this engineering mechanics tutorial, we solve a classic bending stress problem using beam theory and mechanics of materials. You’ll learn how to calculate the maximum allowable uniformly distributed load (UDL) on a simply supported rectangular beam given a bending stress limit and moment of inertia. This video is perfect for students in: Mechanical Engineering Civil Engineering Structural Design Strength of Materials Watch as we guide you step-by-step through the beam bending formula and derive safe load capacity under stress limits. An essential problem for anyone learning how to design structural elements! #UDLCalculation #BeamDesign #BendingStress #StrengthOfMaterials #EngineeringMechanics #SimplySupportedBeam #MomentOfInertia #EngineeringMath #TutorJerryAcademy #CivilEngineering #MechanicalEngineering #StructuralEngineering #EngineeringTutorial #FlexuralStress #EngineeringEducation #StressAnalysis #BendingMoment
