Question

If I impose a torque at the center of a beam that has free ends, where would the maximum torsional angle occur.

Answer 1

The maximum torsional angle would occur at the point where , Torque is applied .( Means at the centre of beam )

Explanation :

=> At the free end the torsional angle would be zero , Because there is no torque acting at that point. It can be proved by the formula as shown , If T=0 , torsion angle = 0.

Also, Torsional angle is given as

,

And at the left hand side of the centre , The Length would decrease . Hence torsional angle would also decrease . As from the formula it is clear that torsion angle is propotional to length if all other terms are constant.

If any doubt kindly comment . Thank you.
