The probability that the load on a scaffolding will exceed the design load of 3 tonnes is 0.15. At the same time, the probability that the strength of the scaffolding will be more than 3 tonnes is 0.85. The probability that the scaffolding will fail is

The dry density of a soil is 1.5 g/cc. If the saturation water content were 50%, then its saturated density and submerged density would, respectively, be

Consider the following soil parameters and conditions : 1. Drainage conditions 2. Thickness of layer 3. Initial void ratio 4. Over-burden pressure The magnitude of settlement is influenced by,
