The temperature stresses producing worst effects in the design of arch dams are caused by ______________

The temperature stresses producing worst effects in the design of arch dams are caused by ______________ Correct Answer fall in temperature

The dam moves upstream during the summer and downstream during the winter due to the internal stresses caused by the temperature changes. In stress analysis, the low temperature becomes quite important since these stresses act additive to the reservoir water pressure.

Consider the following statements in respect of arched construction made of voussoirs: 1. The superimposed load is transferred to the sidewalls only by the strength of cohesion of the mortar between the voussoirs. 2. The arch may fail under crushing when the compressive stress or thrust in it exceeds the safe crushing strength of the voussoir material. 3. Every element in the arch is subjected to compression only. 4. Failure of the arch due to the sliding of any voussoir past the adjacent one due to transverse shear can be avoided by reducing the height of the voussoirs. Which of the above statements are correct?

Read the passage and answer the questions that follow. Evaluation of candidate vaccines for COVID-19 should be done on technical parameters and programmatic suitability. An ideal vaccine would provide the following- immunity that is of a high degree (90%+ protective especially against severe illness), broad-scale (against different variants) and durable (at least five years if not lifelong); a vaccine that is safe (little or no side effects and definitely no serious adverse effects); a vaccine that is cheap (similar to current childhood vaccines); a vaccine that is programmatically suitable- single dose, can be kept at room temperature or at worst needs simple refrigeration between 2 degrees Celsius and 4 degrees Celsius, needle-free delivery, and a vaccine that is available in multi-dose vials, has long shelf life and is amenable to rapid production. Obviously, a vaccine having all these desirable characteristics is a pipe dream, and most vaccines fare well in some and not so well in other parameters, making it difficult to choose between them. What is the most appropriate meaning of the phrase PIPE DREAM?
