Pick up the incorrect statement from the following : The torsional resistance of a shaft is directly proportional to
modulus of rigidity
angle of twist
reciprocal of the length of the shaft
moment of inertia of the shaft section.
Answer: Option
No answer description is available. Let's discuss.

Because Torsional resistance is proportional to Polar moment of inertia (J) and has no relation with the moment of inertia (I).

But it directy propotional to shearmodulus also.

Rajendra said:   5 years ago
T/J is a Polar moment of inertia.

Keshav raidas said:   7 years ago
According to me, it is a polar moment of inertia.

SUKUMAR MALOTH said:   7 years ago
Here T/radius = G * TITA/L , so T is directly proportional to TITA.

Mohan kumar said:   7 years ago
We know T/I=C0/L
T/0 = CI/L
So, T is proportional to the moment of inertia of shaft.
