Applied Mechanics and Graphic Statics A weight ‘W’ is suspended at the free end of a light member hinged to a vertical wall. If the angle of inclination of the member with the upper wall is θ°, the force introduced in the member, is W sin θ W cos θ W sec θ W cosec θ W sin θ W cos θ W sec θ W cosec θ ANSWER DOWNLOAD EXAMIANS APP
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 3 1/3 1/4 4 3 1/3 1/4 4 ANSWER DOWNLOAD EXAMIANS APP
