A rigid bar ABCD is pinned at point B and supported by springs at A and D as shown in the figure below. The springs at A and D have stiffnesses k1 = 10 kN/m and k2 = 25 kN/m, respectively. If the angle of rotation of the bar due to the action of the load P is limited to 30, calculate the maximum permissible load Pmax that can be applied.
