Question

(7 Pts.) Consider the beam with the rectangular cross section shown below. The beamhas internal resultant loadings on the cross section at point C with directions shown inthe free body

diagram of the left side section BC. The magnitudes of these internalloadings are Nc= 312 N, Vc= 180 N, and Mcfind these or draw any FBD§),360 N•m (Note: you do not need to (a) Determine the state of stress located at point D on the beam's cross section. (3 Pts.) (b) Determine the state of stress located at point E on the beam's cross section. (3 Pts.) (c) Draw a 2-D element representing the state of stress for part (b) at point E. (1 Pt.)
