## Homework Statement

One end of a horizontal string of linear density 4.7 multiplied by 10-4 kg/m is attached to a small-amplitude mechanical 58 Hz vibrator. The string passes over a pulley, a distance L = 1.50 m away, and weights are hung from this end, Fig. 11-48. Assume the string at the vibrator is a node, which is nearly true.

What mass must be hung from this end of the string to produce a standing wave with the following number of loops?

a). one loop: ?

b). two loops: ?

c). five loops: ?
