1. The problem statement, all variables and given/known data Suppose a harp string is tuned to middle C (C4) and is 0.56m long. If I want the tension to be 193.5 N, what mass per unit length do I need the harp string to be? Calculate your answer in kg.m 2. Relevant equations Vs = sqrt(T/μ) V = fλ 3. The attempt at a solution Having a very hard time. I looked up the frequency of a C4= 261.61 Hz. I calculated Vs as 261.61 x 1.12 = 293. Then I attempted (293 x 193.5)sq, but that number is way too high. I am stuck.
