A steel bar \(E = 210\text{ GPa}\) and \(\sigma_{yp} = 280\text{ MPa}\) of \(b = 50\text{ mm}\) by \(h = 25\text{ mm}\) rectangular cross section and length \(L = 1.5\text{ m}\) is eccentrically compressed by an axial load \(P = 10\text{ kN}\). The force is applied at 10 mm away from the centroidal longitudinal axis. Calculate (a) slenderness ratio and material constant of the bar and (b) the maximum deflection and maximum bending moment.
