Applied Mechanics and Graphic Statics The gravitational force makes a satellite go round the earth in a circular orbit, if it is projected with an initial velocity of 8.04 km/sec at a height of 285 km 11.26 km/sec, the satellite escapes the pull of the earth 11.11 km/sec at a height of 37,400 km All listed here 8.04 km/sec at a height of 285 km 11.26 km/sec, the satellite escapes the pull of the earth 11.11 km/sec at a height of 37,400 km All listed here ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Two parallel forces 20 kg and 15 kg act. In order that the distance of the resultant from 20 kg force may be the same as that of the former resultant was from 15 kg, the 20 kg force is diminished by 8.75 kg 6.25 kg 10.5 kg 5.5 kg 8.75 kg 6.25 kg 10.5 kg 5.5 kg 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* 1 e*72 e2* e4* 1 e*72 e2* ANSWER DOWNLOAD EXAMIANS APP
