1. The problem statement, all variables and given/known data A steel cable, of cross-sectional area 2.79 * 10^-3 m2, is kept under a tension of 1.00 * 10^4 N. The density of steel is 7860 kg/m3 (this is not the linear density). At what speed does a transverse wave move along the cable? 2. Relevant equations velocity = sqroot(T/(m/L)) m/L = linear density 3. The attempt at a solution I have no idea where to start this because I do not know what to do with the area given and also how to convert the regular density to linear density. Can anyone start me off? i then would know how to solve the problem, thanks!
