Torsional Pendulum Calculator

Length of the spring, l: m
Moment of inertia of bob, I0: kgm2
Torsional rigidity,kt: Nm2
Period, t: t

The torsion spring is a spring that works by torsion or twisting.

Torsional Pendulum Formula

t = 2pi sqrt( l I0 / kt)

where kt = Torsional Rigidity [Nm2], I0 = Moment of Inertia of Bob [kgm2], l = Length of the spring[m]pi = Constant(3.14), t = Period [s]. provides you helpful and handy calculator resources.
