Applied Mechanics and Graphic Statics A rope is wrapped twice around a rough pole with a coefficient of friction ‘A . It is subjected to a force Fj at one end and a gradually increasing force F2 is applied at the other end till the rope just starts slip-ping. At this instant the ratio of F2 to Fi is 1 e*72 e2* e4* 1 e*72 e2* e4* 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 40 m/sec 15 m/sec 50 m/sec 25 m/sec 40 m/sec 15 m/sec ANSWER DOWNLOAD EXAMIANS APP
