For the dual-wheel carrying assembly shown in the figure, P is the load on each wheel, a is the radius of the contact area of the wheel, s is the spacing between the wheels, and d is the clear distance between the wheels. Assuming that the ground is an elastic, homogeneous, and isotropic half space, the ratio Equivalent Single Wheel Load (ESWL) at depth z = d/2 to the ESWL at depth z = 2s is ________. (round off to one decimal place)
(Consider the influence angle to be 45° for the linear dispersion of stress with depth)
