The beam ABCD is loaded as shown. Use the following values in your working out: L = 650 mm F = 10 KN w = 6 kN/m 1 B 3 I L 'c a) Using discontinuity functions/Macauley brackets, write the bending moment equation as a function of x in terms of the unknown reaction forces at A and C. Clearly state what your chosen sign convention is for x. (0.75 marks) b) Which elastic curve diagram best represents the shape of the resulting deflection of the beam? (0.5 marks) F 2 B 4 1 B. L C W ic c) Using the double integration method, determine the magnitude of the reaction forces at A and C. (1.75 marks)
