Applied Mechanics and Graphic Statics One end of an elastic string of natural length / 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 None of these a rectilinear motion with constant speed a damped oscillatory motion a simple harmonic motion None of these a rectilinear motion with constant speed a damped oscillatory motion ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A particle moves in a straight line and its position is defined by the equation x = 6 t² - t3 where t is expressed in seconds and ‘x’ in meters.

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 20 m/sec 50 m/sec 40 m/sec 30 m/sec 20 m/sec 50 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
