A rod of length $$L$$ having uniform cross-sectional area $$A$$ is subjected to a tensile force $$P$$ as shown in the figure below. If the Young’s modulus of the material varies linearly from $${E_1}$$ to $${E_2}$$ along the length of the rod, the normal stress developed at the section $$-$$ $$SS$$ is GATE ME 2013 Strength of Materials - Simple Stress and Strain Question 30 English

MCQ (Single Correct Answer)

-0.3

A steel rod of length $$L$$ and diameter $$D$$, fixed at both ends, is uniformly heated to a temperature rise of $$\Delta T.$$ The Young's modulus is $$E$$ and the coefficient of linear expansion is $$'\alpha '\,.$$ The thermal stress in the rod is

$$0$$

$$\alpha \Delta \,T$$

$$E\alpha \Delta \,T$$

$$E\alpha \Delta \,TL$$

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

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

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

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

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