Applied Mechanics and Graphic Statics If g1 and g2 are the gravitational accelerations on two mountains A and B respectively, the weight of a body when transported from A to B will be multiplied by g2/g1 g1 g1/g2 g2 g2/g1 g1 g1/g2 g2 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

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 50 m/sec 40 m/sec 30 m/sec 20 m/sec 50 m/sec 40 m/sec 30 m/sec ANSWER DOWNLOAD EXAMIANS APP
