Applied Mechanics and Graphic Statics A ball moving on a smooth horizontal table hits a rough vertical wall, the coefficient of restitution between ball and wall being 1/3. The ball rebounds at the same angle. The fraction of its kinetic energy lost is 43833 43839 44052 43864 43833 43839 44052 43864 ANSWER DOWNLOAD EXAMIANS APP
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 e4* e*72 1 e2* e4* e*72 1 e2* ANSWER DOWNLOAD EXAMIANS APP
