## Applied Mechanics and Graphic Statics Two objects moving with uniform speeds are 5 m apart after 1 second when they move towards each other and are 1 m apart when they move in the same direction.The speeds of the objects are:

4 m/sec and 6 m/sec
3 m/sec and 3 m/sec
3 m/sec and 2 m/sec
2 m/sec and 2 m/sec

100 kg
130 kg
150 kg
120 kg

## Applied Mechanics and Graphic Statics If two forces are in equilibrium, then the forces must (i) Be equal in magnitude (ii) Be opposite in sense (iii) Act along the same line

All (i), (ii) and (iii)
(i) and (iii)
Only (i)
(i) and (ii)

## Applied Mechanics and Graphic Statics A cylinder will slip on an inclined plane of inclination 0 if the coefficient of static friction between plane and cylinder is
