Applied Mechanics and Graphic Statics Two parallel forces 20 kg and 15 kg act. In order that the distance of the resultant from 20 kg force may be the same as that of the former resultant was from 15 kg, the 20 kg force is diminished by 5.5 kg 8.75 kg 6.25 kg 10.5 kg 5.5 kg 8.75 kg 6.25 kg 10.5 kg 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 43834 43833 3 4 43834 43833 3 4 ANSWER DOWNLOAD EXAMIANS APP
