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 e4* e2* e*72 1 e4* e2* e*72 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics When a body slides down an inclined surface, the acceleration (f) of the body, is given by f = g cos θ f = g f = g tan θ f = g sin θ f = g cos θ f = g f = g tan θ f = g sin θ ANSWER DOWNLOAD EXAMIANS APP
