1、Chapter 8 Applications of Plane Stress (Pressure Vessels,Beams,and Combined Loadings)Mechanics of Materials8.1 IntroductionPlane stressA common stress condition that exists in all ordinary structures,including buildings,machines,vehicles,and aircraft.Applications with thin,flat structures or parts,s
2、uch as bracket.Airships rely on internal pressure to maintain their shape using a gas lighter than air for buoyant lift.ExamplesStructures to be discussed1.pressure vessels:such as compressed-air tanks and water pipes.2.stresses in beams:determine the principal stresses and maximum shear stresses at various points.3.structures subjected to combined loadings:combinations of axial loads,torsional loads,bending loads,and internal pressure.ObjectiveTo determine the maximum normal and shear stresses at various points in these structures.End
