parietal pleura. The serous membrane that lines the chest cavity; it extends from the mediastinal roots of the lungs and covers the sides of the pericardium to the chest wall and backward to the spine. The visceral and parietal pleural layers are separated only by a lubricating secretion.
The allowableerror is the target value Â± 10%. Using theexample above, the serum cholesterol targetvalue was 200 mg/dL. The total error is 200mg/dL x 0.1 = 20 mg/dL and the acceptabletotal error limits is 180 to 220 mg/dL.First, always determine if within run isacceptable.
The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material. The allowable stresses are generally defined by building codes, and for steel, and aluminum is a fraction of their yield stress (strength): In the above equation, is the allowable stress, is the yield stress, and is the factor of safety or safety factor. This factor is generally defined by the building codes based on particular condition under consideration.
