Problem A3:
In the figure above, the two objects are in static equilibrium, with one on the inclined
plane and the other hanging down. The object on the inclined plane has a mass of
n_{1} Kg, and the hanging object has a mass of n_{2} Kg. Treat the
strings as massless and the pullys as frictionless. If the sin of the angle
&theta in the figure is sin &theta = 1/n_{3} , what is
n_{3}?
