Then, if the outside cylinder is free to move - 2a2 2 X 1 = 0, T T = b2 a2, 7rpa 2 Ub 2+ a 2.
If we compare (I) with the general equation of the second degree ua2 + v/ 32 +wy2 this equation to represent a circle we must have - kabc =vc 2 +wb 2 -2u'bc=wa g +uc 2 - 2v'ca = ub 2 +va - 2w'ab.
Walt Disney and his partner, Ub Iwerks, released the first cartoon with synchronised sound in 1928.
