Applied Mechanics and Graphic Statics In case of S.H.M. the period of oscillation (T), is given by T = 2/ω T = 2π/ω T = 2ω/π² T = π/2ω T = 2/ω T = 2π/ω T = 2ω/π² T = π/2ω 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 25 m/sec 15 m/sec 40 m/sec 50 m/sec 25 m/sec 15 m/sec 40 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 50 m/sec 40 m/sec 30 m/sec 20 m/sec 50 m/sec 40 m/sec 30 m/sec 20 m/sec ANSWER DOWNLOAD EXAMIANS APP
