A fixed-end beam is subjected to a point load at mid-span. The beam has a rectangular cross section (assume that the ratio is 2) and is made of wood (E = 11 GPa). (Solve this problem by integrating the differential equations of the deflection curve. The beam has constant flexural rigidity EI.) P = 11.2 kN A B L= 4 m- (a) Find height h (in mm) of the cross section if the maximum displacement of the beam is 1.6 mm. mm (b) Calculate the displacement of the beam (in mm) at the inflection points. (Enter the magnitude.) mm /7 17
