Negative skin friction in the soil is considered when the pile is constructed through a: Correct Answer Fill material

Negative skin friction is experienced when the soil around the pile settles at a faster rate than a pile. Thus, piles installed in freshly prepared fills of soft compressive deposits are subjected to a downward drag. This downward drag on the pile surface, where the soil moves down relative to the pile, to the structural loads and is called negative skin friction.

From the three typical cases C1, C2, C3 choose the combination, where one can expect occurrence of negative skin friction, on piles: C1 : An upward drag exists in the pile C2 : Develop if the filled material around pile is a loose sand deposit. C3 : Lowering of ground water table resulting in consolidation of soil
Which of the following is NOT true about Frictional force? A. Friction is the force which opposes the relative motion of two surfaces in contact. B. The force of friction that acts when a body is moving (sliding) on a surface is called sliding friction. C. Friction in machines wastes energy and also causes wear and tear. D. Rolling friction is much more than sliding friction, the use of ball bearings in a machine considerably reduces friction.

Consider the following statements: 1. The kinetic friction is always less than the rolling friction. 2. The kinetic friction is always equal to the rolling friction. 3. The kinetic friction is always greater than the rolling friction. Which of the following statement is correct?
A tattoo is a permanent mark or design made on your skin with pigments inserted through pricks into the skin's top layer. Typically, the tattoo artist uses a hand-held machine that acts much like a sewing machine, with one or more needles piercing the skin repeatedly. With every puncture, the needles insert tiny ink droplets. Tattoos carry the risk of creating skin diseases, allergic reactions, and further MRI complications.Since tattoo instruments come in contact with blood and bodily fluids, diseases may be transmitted if the instruments are used on more than one person without being sterilised. However, infection from tattooing in clean and modern tattoo studios employing single-use needles is rare. Assuming the information in the above paragraph is true, which of the following is true?
Consider the following statements: 1. According to Terzaghi, the average angle of wall friction may be taken equal to two-thirds of the respective angle of internal friction. 2. Wall friction increases the active earth Pressure and also decreases the passive earth resistance of the soil 3. Wall friction decreases the active earth pressure and increases the passive earth resistance of the soil. Which of the above statements is/are Correct?
In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed
