1、Chapter 10 Statically indeterminate beams Mechanics of MaterialsIntroductionWelcome to mechancis of materials,in this video,we will start learn the chapter 10 in this course,Statically indeterminate beams.10.1 Introduction 10.2 Types of statically indeterminate beams10.3 Analysis by the differential
2、 equations of the deflection curve 10.4 Method of superpositionOutline These are the topics we will look at here.We are now doing the introduction for this chapter,then we will look at different types of statically indeterminate beams,and then we move to methods for analyzing a statically indetermin
3、ate beam,especially the second method-superposition.Statically indeterminate beamsStatically determinate beams:-the number of reactions the number of independent equations of equilibrium.-the number of reactions =the number of independent equations of equilibrium.Statically indeterminate beamsIn the
4、 previous study of*beams in this course,all reactions,shear forces,and bending moments of beams can be obtained from free-body diagrams and equations of equilibrium,because*the number of reactions euqals to the number of independent equations of equilibrium,such beams are said to be*statically deter
5、minate beams.Then,knowing the shear forces and bending moments,the stresses and deflections are computed.But for*beams with*redundancies,the reactions of such beams cannot be determined by statics alone,becuase in those beams*the number of reactions exceeds the number of independent equations of equ
