A cantilever beam of length 6 m has an additional support at a distance of 2 m from its free end as shown in Figure 4. It has the cross-sectional dimensions with height h=300 mm, inside height h₁ =250 mm, width b= 150 mm, and inside width b₁=100 mm. It is made of an elastic perfectly plastic material having tensile and compressive yield stress of oy = 250 MPa. a) Determine the yield moment My of the beam (5 marks) b) Determine the plastic moment Mp of the beam (5 marks) c) By using force method and selecting the vertical reaction at C to be redundant, draw shear and bending diagrams using the graphical method. d) Determine the minimum value of Wat which collapse occurs (10 marks) (5 marks) B/2W C X 2m 2m 2m C b₁
