Explanation:

To understand why option B is the correct answer, let's break down the given information and analyze each statement.

Statement a: each wheel load acts independently up to a depth d
This statement implies that the load from each wheel in the dual wheel assembly is distributed independently up to a certain depth, which is equal to the distance between the walls of the wheels (d). This means that the load from one wheel does not affect the load distribution of the other wheel.

Statement b: total stress due to dual wheels at any depth greater than 2S is equivalent to a single wheel load of magnitude 2P
This statement suggests that when the depth is greater than twice the center-to-center distance between the dual wheels (2S), the total stress due to the dual wheels can be considered as a single wheel load with double the magnitude (2P). In other words, the load from both wheels in the assembly acts as a single concentrated load.

Statement c: total stress due to dual wheels at any depth greater than S is equivalent to a single wheel load of magnitude 2P
This statement is incorrect because it states that the total stress due to the dual wheels becomes equivalent to a single wheel load at a depth greater than the center-to-center distance between the wheels (S). However, this is not accurate since the load distribution of the dual wheels would still be influenced by the presence of the other wheel.

Statement d: total stress due to dual wheels at any depth greater than 2d is equivalent to a single wheel load of magnitude P
This statement is incorrect because it suggests that the total stress due to the dual wheels becomes equivalent to a single wheel load at a depth greater than twice the distance between the walls of the wheels (2d). However, this is not accurate as the dual wheel assembly would still distribute the load differently compared to a single wheel.

Therefore, the correct answer is option B: total stress due to dual wheels at any depth greater than 2S is equivalent to a single wheel load of magnitude 2P. This statement accurately reflects the behavior of a dual wheel assembly where the load from both wheels acts as a single concentrated load when the depth exceeds twice the center-to-center distance between the wheels.

The question deals with the concept of Equivalent single wheel load.
Equivalent single wheel load (ESWL) is a hypothetical concept as it assumes that the single wheel load will have same properties as that of dual wheel assembly at a particular depth so that it can replace the dual wheel assembly.
Based on the following assumption, a load distribution diagram for dual wheel assembly is depicted below:

where P is the wheel load, S is the center to center distance between the two wheels, d is the clear distance between two wheels, and z is the desired depth.
From the diagram, it can be observed that total stress due to dual wheels at any depth greater than 2S is equivalent to a single wheel load of magnitude 2P.
