A standard penetration test was performed on a particular cohesionless soil. The soil has a unit weight of 20.04 kN/m3. The standard penetration resistance value, measured as blows per foot, was recorded as N = 38.
A rectangular piece of wood,50 mm by L00 mm in cross-section, is used as a compression block as shown in the figure. The grain makes an angle of 20 with the horizontal,as shown
A parabolic cable carries a horizontally distributed load of 5KN/m. The horizontal span between supports A and B is 60 m, with B 10 m higher than A. The cable sags a distance of 5 m below the imaginary line joining A and B at the midspan.
The temporary earth-retaining wall shown consists of planks driven vertically into the ground. The soft, muddy earth creates a triangular pressure against the planks, with max. pressure at the bottom of 12KN/m2Neglecting the weight of the 300 mm-wide plank...
