Question

π a solid is allowed to expand when heated, it will expand in all directions. In this case Where delta V is the change in volume, V, is the initial volume and delta T is the change in Temp. Show, mathematically, that β-3a as per your lecture notes. The magnificent American engineering feat of the HOOVER DAM in Nevada/Arizona was constructed using 3.3 million cubic meters of concrete (at an average annual temperature of 15"C) and a lot of steel. Considering just the concrete, if the temperature in the area of the dam varies from a cold temp of 4'C and a high of 27"C, what increase in volume will the dam experience (from build size) when the temperature gets to be 27"C7( the α for concrete is 1.2x o-/c) 4.
