Sketch the free body diagram for the beam. ü. Determine the reactions at supports A and C. By using A as the origin, write the shear force and bending moment as a function of x for section BC iv. Sketch the shear force and bending moment diagrams for the beam and label their values at all important points. All workings must be shown clearly. No mark will be given to the answers without showing clearly the workings. (6 marks) 5 KN 4 kN/m B D 1.5 m 1.5 m 1.5 m 1 Figure Q1g

It's a problem of Mechanics of Solids. Kindly show all the works.

Answer 1

@ moment is constant Pure bending is a condition where throughout the length of beam only and it happens in case a P LSM = Pxd. gme ܟܟܫ th-exe BMD BMD Any . © O Point of contra Rechire is a point where bending moment changes its sign (positive to negative or negative to positive) Ie * k Point of controeflecture Happens in Ang : only case ©
