In liquid limit test, one experiment was conducted to get 30 blows for a 12.5 mm groove closure for a soil sample and the corresponding moisture content was 0.36. The liquid limit of this soil sample is expected to be close to ……………………………… percent.  Select one: a. 36 b. 37 c. 38 d. 39

You are working in a lab and are tasked with determining the percent plant available water for a particular soil sample.    You take a field soil sample. The mass of your sample was 152g and it had 18.3% moisture by mass.   Then, you place the soil sample in your pressure plate extractor and determine that the soil sample weighs 164.2g when the moisture potential is -33kPa and 130.7g at -1500kPa.    What is the percent plant available moisture by mass of this soil sample? Please answer to one decimal place.

A single angle tension member, L 4 x 4 x 3/8 in. made from A36 steel is connected to a gusset plate with 5/8 in. diameter bolts, as shown in Figure below. The service loads are 35 kips dead load and 15 kips live load. Determine the adequacy of this member using AISC specification. Assume that the effective net area is 85% of the computed net area. |"" d = 5/8 in. Loa Gusset plate L4x4x3/8 Section a-a

A permeability test was conducted on a saturated sample of coarse soil. The soil specimen has a 170 mm diameter and a length of 300 mm. hi and hz was 800 mm and 300 mm respectively. The permeabili this sample in cm/sec is 3.96 10 Time required to collect a volume equal to 350 cm at 20°C is: Select one: 4 min 5 min 4 sec 5 sec ge Teo
