A uniform rod of length and cross-sectional area is heated from to . If the coefficient of linear expansion is , and it is allowed to expand freely, what is the thermal stress developed?
Options:
Answer:
B
Solution:
Thermal stress develops when a material is heated or cooled and its expansion or contraction is constrained.
If the rod is allowed to expand freely, there are no external constraints preventing its deformation. Therefore, no internal restoring forces (and thus no stress) will be developed.
