Applied Mechanics and Graphic Statics The displacement of a particle which moves along a straight line is given by S = 4t³ + 3t²- 10 where ‘S’ is in meters and t is in seconds. The time taken by the particle to acquire a velocity of 18 m/sec from rest, is 1.2 sec 1 sec ½ sec 1.5 sec 1.2 sec 1 sec ½ sec 1.5 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 4 1/4 3 1/3 4 1/4 3 1/3 ANSWER DOWNLOAD EXAMIANS APP
