A box is suspended by a steel wire via a frictionless pulley
The wire has a mass pr length of µ = 24.5 × 10 - 3 kg/m.
The box is so heavy and the wire so thin that the mass of the wire does not influence the wire tension.
The horizontal part of the wire has a length l = 1 m and it is observed that the lowest frequency for standing waves on this part is f1 = 29.6 Hz.
What is the mass M of the box?
