This is done by employing a factor ot satety Unfortunately, increasing the strength of a component in the interests of safety not only increases the initial material costs, but also the operating costs. For example, the stronger and heavier the structure members of an aircraft, the fewer passengers it can carry and the more fuel it consumers. Therefore a balance has to be maintained between safety, initial cost and operating costs. The designer is constantly striving to improve the former whilst reducing the latter
