UKSSSC SAMPLE PAPER 1- In a liquid limit test, the moisture content at 10 blows was 70% and that at 100 blows was 20%. The liquid limit of the soil, is A- 35% B- 50% C- 65% D- 60% 2- The active earth pressure of a soil is proportional to (where φ is the angle of friction of the soil) A- tan (45° - φ) B-cot2 (45° + φ/2) C- tan2 (45° - φ/2) D- tan (45° + φ) 3-An ideal vertical curve to join two gradients, is A- circular B- parabolic C- elliptical D- hyperbolic 4-The angle of internal friction of clays, is usually A- 0° to 5° B- 5° to 20° C- 20° to 30° D- 30° to 45° 5- pore water pressure is equal to- A- Total pressure-effective stress B- Total pressure+effective stress C- effective stress-total pressure D- non of these 6- minimum ranging rod required for indirect ranging is- A- 3 B- 4 C- 5 D- 6 7- throat thickness of fillet weld is- A- T= k× size of weld B- T = 0.7×size of weld C- T = 5/8× thickness of thinner member D- T = 3/5× thickness of thinner member 8- Maximum shear stress for
