A heavy piece of hanging sculpture is suspended by a 90 cm long, 5.0 g steel wire. When the
wind blows hard, the wire hums at its fundamental frequency of 80 Hz. What is the mass of the
28.8=(mass sculpture + mass wire)*g
..im not sure where I am going wrong...or if any of this is correct..
but the string is one half wavelength long (fixed at both ends), so
from the wave equation
put in 80 hz, solve for mass of the weight.
oops, change my .005kg to .05kg
