1. The problem statement, all variables and given/known data A winch cable has a cross sectional area of 1.5 cm^2 and a length of 2.5 m. Young's modulus for the cable is 150 GN/m^2. A 950-kg engine block is hung from the end of the cable. (a) By what length does the cable stretch? (b) If we treat the cable as a piece of string, what is the oscillation frequency of the engine block at the end of the cable? 2. Relevant equations f=1/T=[tex]\omega[/tex]/2[tex]\pi[/tex] 3. The attempt at a solution For (a) I used Young's modulus and found that the cable stretches 0.104 cm. For (b) I don't know how to go about finding the frequency. Thanks.
