For a well graded soil, both uniformity coefficient and coefficient of gradation are nearly unity. A soil is said to be well graded if it has most of the particles of about the same size. all of the above. Pick up the correct statement from the following: * To an agriculturist, soil is the substance existing on the earth's surface, which grows and develops plants To a geologist, soils the material in a relatively thin surface zone within which roots oceur, and rest of the crust is termed as rock irrespective of hardness, To an engineer, soil is the unaggregated and uncemented deposits of minerals and organic particles covering the earth's crust All of the above The bulk density of a soil is defined as the unit weight of the soil solids. * true false
For the beam shown, the magnitude of the concentrated load is P = 11 kN, the magnitude of the couple is MB = 190 kN-m, and the beam lengths are a = 4.9 m and b= 14.7 m. (a) derive equations for the shear force V and the bending moment M for any location in the beam. Place the origin at point. A. (b) use the derived functions to plot the shear-force and bending-moment diagrams for the beam. Use your diagrams to determine the magnitudes of the maximum shear force and the maximum bending moment. Note that answers may be positive or negative. Here, "maximum" refers to the largest magnitude value, but you should enter your shear force and bending moment with the correct sign, using the sign convention presented in Section 7.2 of the textbook. If the magnitudes of the largest positive and largest negative values are the same, enter a positive number. A MB B b C X
