Applied Mechanics and Graphic Statics One end of an elastic string of natural length ‘l’ and modulus ‘X’ is kept fixed while to the other end is attached a particle of mass m which is hanging freely under gravity. The particle is pulled down vertically through a distance ‘x’, held at rest and then released.The motion is A simple harmonic motion A damped oscillatory motion None of these A rectilinear motion with constant speed A simple harmonic motion A damped oscillatory motion None of these A rectilinear motion with constant speed ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If the angle of projection is double the angle of inclination (α) of the plane on which particle is projected, the ratio of times of flight up the inclined plane and down the inclined plane, will be 2 cos α ½ cos α ½ tan α ½ sin α 2 cos α ½ cos α ½ tan α ½ sin α ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 50 m/sec 15 m/sec 25 m/sec 40 m/sec 50 m/sec 15 m/sec 25 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
