To what tension must a spider adjust a 14cm -long strand

Reference no: EM13337439

Biologists think that some spiders "tune" strands of their web to give enhanced response at frequencies corresponding to those at which desirable prey might struggle. Orb spider web silk has a typical diameter of 20?m, and spider silk has a density of 1300 kg/m3.

To have a fundamental frequency at 150Hz , to what tension must a spider adjust a 14cm -long strand of silk?
