Maximum dry density can be obtained through test in the lab by adding the certain amount of water. So in fact the water content is just the additional data. The Answers is D. This is the definition for the water content. Choice B is not correct because it is not always required and the RC value should be evaluated. So, to find the optimum water content the highest amount of density which represents compaction shall be considered. So, the maximum density happens when the water content is The uniformity of 4 shows the soil is classified between SP-SM because it is not between 1 and 3 or greater than 4.

How sweet is that? The Ultimate Equation Reference Guide is like those notes you took in college when you simply got to the point and circled the final equation to know. So, this is the instable structure: Then before any actions occures in this structure the structure will fail and thus there is no bending moment in this structure.
That being known answers C and D are eliminated. To determine the relative compaction we must determine the dry unit weight of the fill sample. Then we can compare it to the maximum dry unit weight. Thus the distribution of bending moment in both direction needs reinforcement for negative and positive bending moment in both directions. A Trained person B Site supervisor C Competent person D anyone in the site with engineering degree The Answers is A The competent person is not necessarily have sufficient knowledge about the nailing.

Short Cut There is no need to calculate anything in this problem. Task 5 is the finishing task of this project and therefore, must be on the critical path. All tasks that are on critical path have always zero floats. Therefore, A is the correct answer. There is no variable material on scaffolding so only the live load of the personnel and their equipment shall be considered. The area on each column is less than sf so no reduction of live loads shall be considered.
The Answers is B According to the below picture and using any different expressions to find the ultimate bearing stress i. So the more depth, the more bearing stress. So the footing which is embedded shows more bearing more than the on surface footing with the same size. Knowing this we will calculate required spacing using the appropriate relationships.
