= In the figure, an aluminum wire, of length L₁ = 34.2 cm, cross-sectional area 2.93 x 102 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 5.5 kg. is arranged so that the distance L₂ from the joint to the supporting pulley is 29.6 cm. Transverse waves are set up in the wire by using an external source of variable frequency; a node is located at the pulley. (a) Find the lowest frequency that generates a standing wave having the joint as one of the nodes. (b) How many nodes are observed at this frequency, including the end nodes? Aluminum (a) Number Units (b) Number Units L Steel
