1. A 3-mm diameter tube is inserted in mercury and in water. a. Assuming the tube is clean so that the angle of contact with mercury is 140 degrees and the surface tension is 0.5140 N/m, what is the amount of depression? b. What is the amount of rise of water inside the tube assuming an angle of contact of 0 degree and a surface tension of 0.0728 N/m? c. If the tube is replaced by two parallel, wide, clean glass plates separated by a distance of 2mm, how far does the water rise due to capillary action assuming surface tension amounting to 0.0730 N/m.

A tensile test was performed on a metal specimen with a diameter of 1 2 inch and a gage length (the length over which the elongation is measured) of 4 inches. The dam were plotted on a load-displacement graph. P vs. L. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P/L =1392 kips/in. What is the modulus of elasticity?

In concrete work, Fuller and Thompson (1907) suggested that a dense packing of grains can be achieved if the percent finer (p) and grain size (D) are related by the following equation, where n is a constant varying in the range of 0.3-0.6. Dmax is the size of the largest grain within the soil. p=(DDmax)n100 This equation is sometimes used in roadwork for selecting the aggregates. a. For n = 0.5, show that the soil is well graded. b. If n = 0.5 and Dmax = 19.0 mm, find the percentages of gravel, sand, and fines within the soil. Use the Unified Soil Classification System.
