(50 marks) (15 marks) Q3. Analytical Question (50 pts) Q3. The following beam OABC has a 200 Nm couple moment applied at the free end C, a 400 N force at point A on its upper surface, and a 100N force applied at point B on the lower surface. The thickness of the beam is 0.4m. a) Replace the loading system acting on the beam by an equivalent force and couple moment at point O b) Replace the loading system acting on the beam by an equivalent single resultant force and specify where the force acts measured from O If the weight of the beam is 500N, 1) Draw the Free Body Diagram of the beam 2) Determine the reactions on the beam at 0 (Conditions of equilibrium are assumed) (15 marks) (5 marks) (15 marks) FA 30° 0.2 m 200 Nm 1.5 m 2 m -1.5 m FB 200N
