Applied Mechanics and Graphic Statics The tension in a cable supporting a lift Is more when the lift is moving downwards Is less when the lift is moving upwards Is less when the lift is moving downwards Remains constant whether its moves downwards or upwards Is more when the lift is moving downwards Is less when the lift is moving upwards Is less when the lift is moving downwards Remains constant whether its moves downwards or upwards 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 50 m/sec 30 m/sec 40 m/sec 20 m/sec 50 m/sec 30 m/sec 40 m/sec 20 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A 49 kg lady stands on a spring scale in an elevator. During the first 5 sec, starting from rest, the scale reads 69 kg. The velocity of the elevator will be 10 m/sec 15 m/sec 25 m/sec 20 m/sec 10 m/sec 15 m/sec 25 m/sec 20 m/sec ANSWER DOWNLOAD EXAMIANS APP
