Applied Mechanics and Graphic Statics A rod 5 m in length is moving in a vertical plane. When it is inclined at 60° to horizontal, its lower end is moving horizontally at 3 m/sec and upper end is moving in vertical direction. The velocity of its upper end, is 1.5 m/sec 0.5 m/sec 1.0 m/sec 2.5 m/sec 1.5 m/sec 0.5 m/sec 1.0 m/sec 2.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
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 20 m/sec 30 m/sec 40 m/sec 50 m/sec 20 m/sec 30 m/sec 40 m/sec 50 m/sec ANSWER DOWNLOAD EXAMIANS APP
