An axial compressive force P acts on the 6 m-long column AB with a square cross-section, whose loading condition and dimensions are given in the figure. Accordingly, find the load P that the column can safely carry without buckling. The B end of the column is fixed and the safety number for buckling is n = 3.

solve the fixed-end moment of the beam shown below using CONJUGATE METHOD. show the step by step solution/ derivation

Question Three The three-bar truss ABC shown in the figure part a has a span L = 3 m and is constructed of steel pipes having cross-sectional area A = 3900 mm² and modulus of elasticity E = 200 GPa. Identical loads P act both vertically and horizontally at joint C, as shown. (a) If P=475 kN, what is the horizontal displacement of joint B? (b) What is the maximum permissible load value Pmax if the displacement of joint B is limited to 1.5 mm? P P A 45° 45° B woobute L (a)
