6.9 What would be the effect on the end deflection for question 6.7, if the built-in end A were replaced by a simple support at the same position and point B becomes a full simple support position (i.e. the force at B is no longer 10 kN). What general observation can you make about the effect of built-in constraints on the stiffness of beams? [5.7 mm] 6.7 A 3 m long cantilever ABC is built-in at A, partially supported at B, 2 m from A, with a force of 10 kN and carries a vertical load of 20 kN at C. A uniformly distributed load of 5 kN/m is also applied between A and B. Determine (a) the values of the vertical reaction and built-in moment at A and (b) the deflection of the free end C of the cantilever. Develop an expression for the slope of the beam at any position and hence plot a slope diagram. E= 208 GN/m² and I=24 × 10-6 m².
