Two wires are welded together end to end. The wires are made of the same material, but the diameter of one
is twice that of the other, di = 2 d2. They are subjected to a tension of T= 4.60 N. The thin wire has a
length of L2 = 40.0 cm and a linear mass density of 2 = 2.00 g/m. The combination is fixed at both ends
and vibrated in such a way that two antinodes are present, with the node between them being right at the
weld.
