In Figure Q1, beam OC is supported by a smooth pin connection at O and supported at B by an elastic rod BD, also through pin connections. A concentrated load F = Y kN is applied at C.Compute the deflection of point C. The modulus of elasticity of the beam is 207 GPa (steel) and the dimensions of the cross section are 40 mm 40 mm. For elastic rod BD, the modulus of elasticity is 69 GPa (aluminum) and the cross-sectional area is 78.54 mm. X = 6.403 Y = 2X 777 10 U D Xmm B 200 mm F C + X mm 3 U3
