Telltale rods A and B have been embedded at points 30 ft and 59 ft from the top of the pile, , Telltale rod A is anchored only 1 ft from the mud line (the top of the soil). There is es- ially no side-friction resistance between the top of the pile and this point, so the force at a depth of 30 ft is essentially the same as that at the top of the pile.
