Applied Mechanics and Graphic Statics A ladder of weight 'w' rests against a smooth vertical wall, and rests on rough horizontal ground, the coefficient of friction between the ladder and the ground being 1/4. The maximum angle of inclination of the ladder to the vertical, if a man of weight 'w' is to walk to the top of it safely, is tan'1 x, where x is 4 1/3 1/4 3 4 1/3 1/4 3 ANSWER DOWNLOAD EXAMIANS APP
