If anyone can see something I have done wrong then please let me know.

Diameter = 60mm = 0.06m

Radius = 0.03m

Length = 1m

Theta = 1 degree = 0.0175rads

Shear modulus = 80 x 10exp9

Torque = G*r*theta/L

Torque = 80 x 10exp9*0.03*0.0175/1

Torque = 42000000

Torque = 42kNm

I think I have answered my own question. Just thought I'd post the answer I got.
