Question:
Toughness Index gives a measure of Shear Strength of soil at ___
Toughness Index gives a measure of Shear Strength of soil at ___
Show Hint
Toughness Index is useful for assessing the shear strength and consistency of cohesive soils, particularly when evaluating their plasticity.
Updated On: May 3, 2025
- Liquid Limit
- Plastic Limit
- Shrinkage Limit
- Dry State
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Toughness Index is defined as the difference between the Plasticity Index and the Liquidity Index. It is used to measure the shear strength of the soil at the plastic limit, which is the state where the soil can still be molded but exhibits some resistance to flow. Hence, the correct answer is the Plastic Limit.

- For a right-hand offset disc harrow, the longitudinal distance from the hitch point to the centers of the front and rear gangs are 2.5 m and 4.5 m, respectively. The resultant horizontal soil forces in longitudinal direction on the front and rear gangs are 3.0 kN and 3.5 kN, respectively; while the resultant horizontal soil forces in lateral directions are 2.5 kN and 4.0 kN, respectively. Considering the resultant soil forces acting at the centers of front and rear gangs, the amount of offset of the center of cut with respect to the hitch point is _________ m.

- To protect a wheat field from wind erosion, windbreaks of 2.7 m height are provided. The actual wind velocity at 15 m height perpendicular to the wind barrier is 9 m.s\(^{-1}\) and the minimum wind velocity at 15 m height required to move the most erodible soil fraction is 9.6 m.s\(^{-1}\). The distance of full protection from this windbreak is _________ m. (Rounded off to 2 decimal places)
- Water flows through a 90° V-notch weir having a discharge coefficient of 0.6. If the depth of water above the notch is 49 cm and the acceleration due to gravity is 9.81 m.s\(^{-2}\), the discharge over the notch is _________ m\(^3\).s\(^{-1}\) (Rounded off to 2 decimal places).
