Question 1 of 5

A uniform, the slender cylindrical rod is made of a homogeneous and isotropic material. The rod rests on a frictionless surface. The rod is heated uniformly. If the radial and longitudinal thermal stresses are represented by \sigma_{r} and \sigma_{z} , respectively, then

A

\sigma_{r} \neq 0, \sigma_{z}=0

B

\sigma_{t} \neq 0, \sigma_{z} \neq 0

C

\sigma_{t}=0, \sigma_{z} \neq 0

D

\sigma_{r}=0, \sigma_{z}=0
