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 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 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The piston of a steam engine moves with a simple harmonic motion. The crank rotates 120 r.p.m. and the stroke length is 2 meters. The linear velocity of the piston when it is at a distance of 0.5 metre from the centre, is 10.88 m/sec 8.88 m/sec 12.88 m/sec 5.88 m/sec 10.88 m/sec 8.88 m/sec 12.88 m/sec 5.88 m/sec 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 20 m/sec 40 m/sec 30 m/sec 50 m/sec 20 m/sec 40 m/sec 30 m/sec 50 m/sec ANSWER DOWNLOAD EXAMIANS APP
