STRESS

Any component, no matter how simple or complex, has to transmit or sustain a mechanical load of some sort. The load may be one of the following types: a load that is applied steadily ("dead" load); a load that f uctuates, with slow or fast changes in magnitude ("live" load); a load that is applied suddenly (shock load); or a load due to impact in some form.  Stress is a form of load that may be applied to a component. Personnel need to be aware how stress may be applied and how it effects the component.
