If I hang a small cylindrical object with a string, I get a pendulum. When I swing it, the object mostly rotates about its axis. What effect does this rotation have on the time period of the pendulum? Can we find out the effect quantitatively?

T = 2π*SQRT(L/g)
so i dont think that the torque would poduce any effect on the time period as T is independent of mass(moment of inertia) in casev of rotating objects
post further questions in physics section as there are good answering people there
@Salini - That relation is only valid for point mass objects.
This is a cylinder.
Hence we have to consider it a torsional as well as physical pendulum according to the question.
That's what you're asking right?
