The correct answer is: B. For a well graded soil, both uniformity coefficient and coefficient of curvature are nearly unity.<\/strong><\/p>\n The uniformity coefficient (Cu) is a measure of the range of particle sizes in a soil. It is defined as the ratio of the d60 (the particle size that is 60% finer by weight) to the d10 (the particle size that is 10% finer by weight). The coefficient of curvature (Cc) is a measure of the shape of the particle size distribution curve. It is defined as the square root of the ratio of the d30 (the particle size that is 30% finer by weight) to the d60.<\/p>\n A well-graded soil is a soil that has a uniform distribution of particle sizes. This means that the d60, d10, and d30 are all close to each other. In a well-graded soil, there are no large gaps between the different particle sizes. This makes the soil more stable and less likely to erode.<\/p>\n The uniformity coefficient and coefficient of curvature are both used to determine the grading of a soil. A well-graded soil will have a uniformity coefficient and coefficient of curvature that are both close to unity.<\/p>\n A soil is said to be well graded if it has most of the particles of about the same size. This is not correct because a well-graded soil has a uniform distribution of particle sizes.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Uniformity coefficient represents the shape of the particle size distribution curve.” option2=”For a well graded soil, both uniformity coefficient and coefficient of curvature are nearly unity.” option3=”A soil is said to be well graded if it has most of the particles of about the same size” option4=”none of the above” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[646],"tags":[],"class_list":["post-6962","post","type-post","status-publish","format-standard","hentry","category-soil-mechanics-and-foundation","no-featured-image-padding"],"yoast_head":"\n
