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 5.5 kg 6.25 kg 10.5 kg 8.75 kg 5.5 kg 6.25 kg 10.5 kg ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Kinetic friction may be defined as Friction force acting when the body is in motion Friction force acting when the body is just about to move Ratio of limiting friction and normal reaction Angle between normal reaction and resultant of normal reaction and limiting friction Friction force acting when the body is in motion Friction force acting when the body is just about to move Ratio of limiting friction and normal reaction Angle between normal reaction and resultant of normal reaction and limiting friction 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 40 m/sec 50 m/sec 30 m/sec 20 m/sec 40 m/sec 50 m/sec 30 m/sec ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A vehicle weighing w kg is to run on a circular curve of radius r. If the height of its centre of gravity above the road level is h and the distance between the centres of wheels is 2a, the maximum velocity, in order to avoid over turning, will be 4√(gra/h) √(gra/h) ∛(gra/h) gra/h 4√(gra/h) √(gra/h) ∛(gra/h) gra/h ANSWER DOWNLOAD EXAMIANS APP
