Choose the correct statement(s) with respect to the Lag distance in co...

The lag distance is given by the simple equation.

Lag distance = Velocity x Reaction Time

Reaction time as per IRC recommendation is 2.5 sec

Lag distance is dependent mainly on Velocity of the moving vehicle and the reaction time and independent on coefficient of longitudinal friction, gradient and efficient of brake.

The reaction time of the driver is the time required to apply the brake after observing the obstruction

A 10 m thick clay layer is resting over a 3 m thick sand layer and is submerged. A fill of 2 m thick sand with unit weight of 20 kN/m3 is placed above the clay layer to accelerate the rate of consolidation of the clay layer. Coefficient of consolidation of clay is 9 × 10–2 m2/year and coefficient of volume compressibility of clay is 2.2 × 10–4 m2/kN.Assume Taylor’s relation between time factor and average degree of consolidation.The settlement (in mm, round off to two decimal places) of the clay layer, 10 years after the construction of the fill, is _________.
