Applied Mechanics and Graphic Statics The acceleration of a train starting from rest at any instant is 1/6(V + 1) m/sec² where ‘V’ is the velocity of the train in m/sec. The train will attain a velocity of 36 km/hour after travelling a distance of 2100 m 2300 m 2000 m 2200 m 2100 m 2300 m 2000 m 2200 m ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A ball moving with a velocity of 5 m/sec impinges a fixed plane at an angle of 45° and its direction after impact is equally inclined to the line of impact. If the coefficient of restitution is 0.5, the velocity of the ball after impact will be 0.5 m/sec 2.5 m/sec 3.5 m/sec 1.5 m/sec 0.5 m/sec 2.5 m/sec 3.5 m/sec 1.5 m/sec 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 1/4 1/3 3 4 1/4 1/3 3 4 ANSWER DOWNLOAD EXAMIANS APP
