Solution

The correct option is B Zero at one end and compression at the other end
$B e a r i n g p r e s s u r e a t b a s e d u e t o a x i a l l o a d = \frac{P}{A}$ .
$S t r e s s a t b a s e d u e t o m o m e n t = \frac{M}{Z}$

$G i v e n \frac{P}{A} = \frac{M}{Z} = σ (s a y)$

$σ_{B} = \frac{P}{A} + \frac{M}{Z} = 2 σ (C o m p r e s s s i v e)$

$σ_{A} = \frac{P}{A} - \frac{M}{Z} = 0$
