I do not understand other commentary and ask.1. The standard penetration tests were conducted at a depth of 6.5 m in the normally consolidated coarse sand deposit and the blow count was 35. A USA donut hammer was employed in the test. The G.W.Τ. is located at a depth of 4.0m. The unit weight of sand above the G.W.T. is 17.5kN/m3, and the saturated unit weight of sand below the G.W.T. is 19.0kN/m3. a) Evaluate Noo and (N)so, b) estimate...

Q) Design the concrete mixture for the slab
2. A reinforced slab concrete foundation is to be poured for a building. The building is to be constructed near Edmonton. The slab will be in direct contact with the soil, and the soil typically has a sulphate content of 0.3 percent by mass. The minimum rebar spacing in the slab is 100 mm. The contractor is certain that his workers can place a concrete with a...

Example 2. The Navy is building a road at a new installation. Pavement base coarse specifications require that the compacted soil must be at least 0.95 Y dima) With moisture content 2% of wopt. The desired base coarse soil was laboratory tested for specific gravity and compaction; results are compiled in Table 1. After compaction of the soil in the field, nuclear density control tests were conducted at five separate locations. The results of the control tests are shown in...

A)The data were collected in a study conducted in a semiconductor manufacturing plant. In this plant the finished semiconductor is wire bonded to a frame. The goal of the study was to relate a pull strength to a wire length and a die height. The variables obtained for each subject were a pull strength (a measure of the amount of force required to break a bond), a wire length, and a height of a die. What is the type of...

1. Procedure A. Lithium 2,6-dimethylphenoxide. In a 300-ml. flask, equipped with a magnetic stirrer and a reflux condenser and flushed with nitrogen, are placed 150 ml. of toluene (freshly distilled from sodium), 1.40 g. (0.202 mole) of lithium metal (Note 1) and 25.0 g. (0.205 mole) of resublimed 2,6-dimethylphenol. The mixture is heated under reflux with stirring for 36 hours; a nitrogen atmosphere is maintained for the reflux period (Note 2). The condenser is replaced by a distillation head with...
