Question 1

What does the tangent PQ represent on the graphical plot?

  • The total pressure applied
  • The rate measured at a point
  • The average of all points

💡 Hint: Think about what tangent lines do in relation to curves.

Question 2

True or False: The consolidation time is the same regardless of the drainage path length.

  • True
  • False

💡 Hint: Consider how drainage paths affect time measurements.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
