J/R is called polar section modulus. Where J is polar moment of inertia.

Since j is polar moment of inertia (pi/32)*d^4 so in that clue we can conclude the solution.

Polar modulus and torsional section modulus are both same. Polar modulus should not be confused with polar moment of inertia.

J/r is polar section modulus.
J is polar modulus,
I is a moment of inertia,
Z is section modulus.
J is polar modulus,
I is a moment of inertia,
