Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a plotted curve of consolidation pressure readings. Explain how to determine where the tangent would touch and its significance for two different materials with varying permeability.

💡 Hint: Consider how quicker drainage would affect the tangent's slope.

Challenge 2 Hard

Given a monotonically increasing curve for time and consolidation, choose a point to draw the tangent and a line PR. Explain how variations in your method might affect the accuracy of predicting consolidation time.

💡 Hint: Think about what would happen with incorrect measurements.
