Please help me with written solutions to these two questions from EJ. Hearn:::5.17 (B). A simply supported beam AB is 7 m long and carries a uniformly distributed load of 30 kN/m run. Acouple is applied to the beam at a point C, 2.5m from the left-hand end, A, the couple being clockwise in sense and ofmagnitude 70 kNm. Calculate the slope and deflection of the beam at a point D, 2 m from the left-hand end. TakeEI = 5 x. lo7 Nm’. [E.M.E.U.] C5.78 x 10-3rad, 16.5mm.l5.18 (B). A uniform horizontal beam ABC is 0.75 m long and is simply supported at A and B, 0.5 m apart, bysupports which can resist upward or downward forces. A vertical load of 50N is applied at the free end C, whichproduces a deflection of 5 mm at the centre of span AB. Determine the position and magnitude of the maximumdeflection in the span AB, and the magnitude of the deflection at C. .[E.I.E.] C5.12 mm (upwards), 20.1 mm.]
