z = f_s*(d_c*A)^(1/3)
This formula uses 4 Variables

Variables Used

Crack Control Limits - (Measured in Pound-Force per Inch) - Crack Control Limits can be described when reinforcement is subjected to high stresses so that there is control limits for cracks.
Stress in Reinforcement - (Measured in Pascal) - Stress in Reinforcement can be defined as the force applied along an the reinforcement upon a cross sectional area of reinforcement.
Thickness of Concrete Cover - (Measured in Meter) - Thickness of Concrete Cover can be described as the length of concrete cover measured from extreme tension surface to center of bar closest to that surface.
Effective Tension Area of Concrete - (Measured in Square Meter) - Effective Tension Area of Concrete can be described as the area surrounding main tension reinforcement.

STEP 1: Convert Input(s) to Base Unit

Stress in Reinforcement: 3.56 Kilonewton per Square Meter --> 3560 Pascal (Check conversion here)
Thickness of Concrete Cover: 1000.3 Inch --> 25.4076200001016 Meter (Check conversion here)
Effective Tension Area of Concrete: 1000.2 Square Inch --> 0.645289032005162 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

z = f_s*(d_c*A)^(1/3) --> 3560*(25.4076200001016*0.645289032005162)^(1/3)

Evaluating ... ...

z = 9043.90699638255

STEP 3: Convert Result to Output's Unit

1583830.81053156 Newton per Meter -->9043.90699638255 Pound-Force per Inch (Check conversion here)

FINAL ANSWER

9043.90699638255 ≈ 9043.907 Pound-Force per Inch <-- Crack Control Limits
