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 damped oscillatory motion A simple harmonic motion A rectilinear motion with constant speed None of these A damped oscillatory motion A simple harmonic motion A rectilinear motion with constant speed None of these 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) 25 m/sec 50 m/sec 15 m/sec 40 m/sec 25 m/sec 50 m/sec 15 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A body is said to move with Simple Harmonic Motion if its acceleration, is Always directed away from the centre, the point of reference Proportional to the square of the distance from the point of reference Proportional to the distance from the point of reference and directed towards it Inversely proportion to the distance from the point of reference Always directed away from the centre, the point of reference Proportional to the square of the distance from the point of reference Proportional to the distance from the point of reference and directed towards it Inversely proportion to the distance from the point of reference ANSWER DOWNLOAD EXAMIANS APP
