FAQs on Thermal Stress Video Lecture - Civil Engineering Optional Notes for UPSC

1. What is thermal stress?
Ans. Thermal stress refers to the stress created in a material due to temperature variations. When a material expands or contracts unevenly due to temperature changes, it can lead to internal stress or strain, known as thermal stress.
2. How does thermal stress affect materials?
Ans. Thermal stress can have various effects on materials. It can cause materials to deform, crack, or even fail. The stress created by temperature changes can weaken the structural integrity of the material and reduce its overall performance and lifespan.
3. What are some common examples of thermal stress in everyday life?
Ans. Thermal stress can occur in many everyday situations. Some common examples include the expansion and contraction of bridges and roads due to temperature changes, the cracking of glass when exposed to hot liquids, and the warping of metal objects when heated or cooled rapidly.
4. How can thermal stress be minimized or controlled?
Ans. To minimize or control thermal stress, various techniques can be employed. These include using materials with low thermal expansion coefficients, designing structures with expansion joints to accommodate thermal expansion and contraction, and implementing insulation to reduce temperature variations.
5. What are some potential consequences of ignoring thermal stress in engineering and construction?
Ans. Ignoring thermal stress in engineering and construction can have significant consequences. It can lead to structural failures, such as the collapse of buildings or bridges, as well as the development of cracks and leaks in pipelines and other infrastructure. Proper consideration of thermal stress is crucial to ensure the safety and longevity of engineered structures.
