4.) Consider the 2D beam supported by a pin-joint at B and a roller at A. EXTERNAL FORCES a) Draw a FBD. Include all external reaction forces & moments. b) Solve for the values of all external reaction forces & moments. INTERNAL FORCES c) Draw the internal shear force diagram (SFD) for the beam. Label the maximum and minimum values on the graph. d) Draw the internal bending moment diagram (BMD) for the beam. Label the maximum and minimum values on the graph. e) What is the bending moment at point C? sagging or hogging? f) What is the bending moment at point D ? sagging or hogging?
