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 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 A damped oscillatory motion A simple harmonic motion ANSWER DOWNLOAD EXAMIANS APP
