Homework Statement
Derive the differential equation governing the longitudinal vibration of a thin cone which has uniform density p, show that it is1/x/SUP] d/dx(x du/dx) = (1/c) d u/dt
Hint: The tensile force sigma = E du/dx where E is the Young's modulus (a constant), u is the longitudinal displacement and x is the longitudinal coordinate.
