It's not J/R.

It is tou/R.

J/r is polar section modulus.

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

T/j is the polar modulus.

Rushi said:   1 decade ago
j is polar moment of inertia.

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

Sai krish said:   1 decade ago
Since j is polar moment of inertia (pi/32)*d^4 so in that clue we can conclude the solution.

Manish said:   1 decade ago
Polar modulus and torsional section modulus are both same. Polar modulus should not be confused with polar moment of inertia.

j = Polar moment of inertia.
r = Radius.

Torsional rigidity means what?

Ranjith babu said:   8 years ago
Only j is the polar moment of innertia.
