In the figure, an aluminum wire, of length L₁ = 513 cm, cross-sectional area 5.00x102 cm², and density 2.60 g/cm³, is joined to a steel wire of density 7.80 g/cm³ and the same cross-sectional area. The compound wire, loaded with a block of mass m = 7.20 kg, is arranged so that the distance from the joint to the supporting pulley is L₂ = 118 cm. Transverse waves are set up on the wire by an external source of variable frequency; a node is located at the pulley.
