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* e4* 1 e*72 e2* e4* 1 e*72 ANSWER DOWNLOAD EXAMIANS APP
