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 e2* e*72 1 e4* e2* e*72 1 e4* ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Ball ‘A’ of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/s hits an identical stationary ball ‘B’ on the table. If the impact is perfectly elastic, the velocity of the ball ‘B’ just after impact would be 10 m/sec 5 m/sec Zero None of these 10 m/sec 5 m/sec Zero None of these ANSWER DOWNLOAD EXAMIANS APP
