PROBLEM 3 The uniform 25 lb-f ladder in the figure below rests against the smooth wall at B, and the end A rests on the rough horizontal plane with coefficient of friction shown in the figure. Determine the angle of inclination (theta) of the ladder and the normal reaction at B if the ladder is on the verge of slipping. B Smooth wall 15 ft. Hg = 0.3 %3D A N(b) = 7.5, 0=59.04° N(b) = 5.5, 0=55.04°
