Bending stresses in beams - Problem 27 | Strength of Materials | Stresses in Beams...

Question: A beam is of square section of the side 'a'. If the permissible bending stress is σ, find the Moment of Resistance when the beam section is placed such that: i) Two sides are horizontal ii) One diagonal is vertical. Find also the moments of resistance of the beam in the two positions. In this Strength of Materials video, we solve an important engineering problem on the Moment of Resistance of a Square Beam under different orientations. You will learn how the position of the square cross-section (sides horizontal vs diagonal vertical) affects the section modulus and hence the moment of resistance. ✅ Step-by-step solution using bending stress formula ✅ Comparison of square beam in two orientations ✅ Concept of section modulus and moment of resistance explained This video is ideal for students preparing for Strength of Materials, Structural Analysis, Solid Mechanics, Civil Engineering, and Mechanical Engineering exams. #MomentOfResistance #SquareBeam #StrengthOfMaterials #SolidMechanics #BeamAnalysis #EngineeringEducation #TutorJerryAcademy #BendingStress #SectionModulus #EngineeringTutorials #MechanicalEngineering #CivilEngineering #EngineeringMechanics #BeamStrength #StructuralEngineering
