Applied Mechanics and Graphic Statics If ‘v’ and ‘ω’ are linear and angular velocities, the centripetal acceleration of a moving body along the circular path of radius ‘r’, will be v²/r ω²/r r/v² r/ω² v²/r ω²/r r/v² r/ω² ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If two forces each equal to ‘T’ in magnitude act at right angles, their effect may be neutralized by a third force acting along their bisector in opposite direction whose magnitude will be √2 T 2 T 1/2 T 3 T √2 T 2 T 1/2 T 3 T 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
