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 e*72 e2* 1 e4* e*72 e2* 1 e4* ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A sphere is resting on two planes BA and BC which are inclined at 45° and 60° respectively with the horizontal.

Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 30 m/sec 50 m/sec 20 m/sec 40 m/sec 30 m/sec 50 m/sec 20 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
