The lowest note on a grand piano has a frequency of 28.1 Hz. The entire string is 2.00 m long and has a mass of 440 g The vibrating section of the string is 1.90 m long. What tension is needed to tune this string properly?

Now this is very similar to one I sketched out for you earlier. Try to do it.
ok, so I came out with 293.3N...what am I doing wrong???
f=1/2L*sqrt(T/lin density)
lin density=m/L
f=1/2L*sqrt(T/(m/L))
lin density=m/L
f=1/2L*sqrt(T/(m/L))
