Applied Mechanics and Graphic Statics A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is 3/4 3/5 4/5 5/3 3/4 3/5 4/5 5/3 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The angle of friction is: The ratio of the friction and the normal reaction The force of friction when the body is in motion The force of friction at which the body is just about to move The angle between the normal reaction and the resultant of normal reaction and limiting friction The ratio of the friction and the normal reaction The force of friction when the body is in motion The force of friction at which the body is just about to move The angle between the normal reaction and the resultant of normal reaction and limiting friction ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 30 m/sec 40 m/sec 50 m/sec 20 m/sec 30 m/sec 40 m/sec 50 m/sec 20 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A particle is dropped from the top of a tower 60 m high and another is projected upwards from the foot of the tower to meet the first particle at a height of 15.9 m.
