Uniformity coefficient Effective size Coefficient of curvature None of the given Uniformity coefficient of a soil is Less than 1 Always greater than or equal to 1 Can be equal to 1 only Can be zero only The neutral stress in a soil mass is Force per neutral area Force per effective area Stress taken up by the pore water Stress taken up by solid particles A soil has a liquid limit of 45% and lies above the A-line when plotted on a plasticity chart. The group, symbol of the soil as per Soil Classification is CH CI CL MI What does the confining pressure used in triaxial compression tests on an undisturbed soil sample represent ? in-situ total normal stress in-situ total lateral stress in-situ effective average principal stress in-situ shear stress Field vane shear is the appropriate field test for obtaining the shear strength of which one of the following Stiff clay Weathered rock Sand Soft clay As per ICAO, the minimum basic runway length for class A airport is 2100m 1500m 1200m 600m The channel whose boundary is not deformable is known as Rigid channel Prismatic channel Mobile channel Boundary channel The discharge in an open channel corresponding to critical depth is Zero Minimum Maximum None of these If the depth of water in an open channel is greater than the critical depth, the flow is called Critical flow Turbulent flow Tranquil flow Torrential flow Redundant frames have members More than that in perfect frame Less than that in perfect frame Equal to that in perfect frame None of the above The statical method in plastic analysis falls under the catagory of Upper bound theorem Lower bound theorem Upper or lower bound method none of the above The ratio of moment produced at a joint to the moment applied at other joint is called Distribution factor Carry over factor Stiffness factor Bending moment Moment required at one end of a member to produce unit angle of rotation at that end is called Distribution factor Carry over factor Stiffness factor Bending moment The maximum permissible stress in axial tension . 0.6fy 0.66 fy 0.4 fy 0.75 fy The shape factor for rectangular section is 1 1.5 2 2.34 For a plate girder, the economical depth corresponds to minimum Depth Width Thickness Weight When the effect of wind or earthquake load is considered in the design of rivets and bolts for steel structures, by what percentage the permissible stresses may be exceeded? 25 33.33 50 100 1 out of 20 Time is Up!
