Solve the all part of following question given below:
Question: A piano has approximately 1000 Newton's (225 lbs) of tension in each string. Although there are only 88 keys in a piano, most of them have 3 strings (the bass strings only have 1 or 2 strings per key), adding up to a total of 230 strings.
Part A: What is the total force inside of a piano in pounds?
Part B: Convert to tons (2000 lbs/ton)
Part C: In 1859 the standard was 435 Hertz for middle "A". In 1939 it was changed to 440 Hz. Assuming the string had 225 lbs on it for 435 Hz, what is the new tension? (Hint; wave speed is proportional to the sqrt of the tension)
Part D: How much has the total force inside of the piano changed?
I need tutor help to solve the above question.
