A) Replace the distributed load with an equivalent concentrated load. B) Draw a free body diagram for the beam showing the forces acting on the beam and their locations. C) Applying the equations of equilibrium, determine the reactions forces at the fixed pin support B and roller support at point C. D) If the aluminium beam is replaced by another iron beam which undergoes an expansion of 0.2 m when heated from 10 C° to 50 C° (Knowing that the coefficient of linear expansion of iron is a =11.7×10-6 K-1. Calculate the original length of the beam. Then suppose that the temperature is decreased from 50 C° to 10 C°, explain how this will affect the length of the beam? 20 kN 40 kN 45 kN/m ↑ † f f t. 12m Figure 1:Beam
