Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The cross-sections of the shaft which are plane before twist, remain plane during and after twist.
Reasons (R): The twisting moment does not vary with the radius of the shaft.
In the light of the above statements, choose the most appropriate answer from the options given below:
Assertion (A): The cross-sections of the shaft which are plane before twist, remain plane during and after twist.
