एक निश्चित रूप से जकड़े हुए ठोस बार में उत्पन्न तापीय प्रतिबल (temperature stress) निम्नलिखित में से किस कारक पर निर्भर करता है?

A brass bar is enclosed inside a steel tube and rigidly fixed at both ends. If the coefficient of thermal expansion of brass is greater than that of steel (αbr > αst), when the temperature of the assembly is increased, the nature of stresses induced in the steel tube and brass bar respectively are:

A uniform, slender cylindrical rod is made of a homogeneous and isotropic material. The rod rests on a frictionless surface and is heated uniformly. If the radial and longitudinal thermal stresses are represented by σr and σz respectively, then:
