MCQ (Single Correct Answer)

-0.3

A uniform, 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

$${\sigma _r} = 0,{\sigma _z} = 0$$

$${\sigma _r} \ne 0,{\sigma _z} = 0$$

$${\sigma _r} = 0,{\sigma _z} \ne 0$$

$${\sigma _r} \ne 0,{\sigma _z} \ne 0$$
