prudent limit of endurance

The time during which an aircraft can remain airborne and still retain a given safety margin of fuel.

Fatigue limit, endurance limit, and fatigue strength 

are all expressions used to 

describe a property of materials: 

the amplitude (or range) of cyclic stress that can be 

applied to the material without causing fatigue failure.^[1]

Ferrous alloys and titanium alloys^[2] have a distinct limit, an amplitude below which there appears to be no number of cycles that will cause failure. 

Other structural metals such as aluminium and copper, 

do not have a distinct limit and will eventually fail even from small stress amplitudes. 

In these cases, a number of cycles (usually 10⁷) is chosen to represent the fatigue life of the material.

And truly the Son of man goeth, as it was determined: but woe unto that man by whom he is betrayed! the Son of man went the  the limit of His endurance He prayed all this night Hematohidrosis also known as Hematidrosis, hemidrosis and hematidrosis, is a condition in which capillary blood vessels that feed the sweat glands rupture, causing them to exude blood, occurring under conditions of extreme physical or emotional stress.[1] Manonukul et al. proposed the term “hematofolliculohidrosis” because it appeared along with sweat-like fluid and the blood exuded via the follicular canals.[5] Various causative factors have been suggested by Holoubek, like component of systemic disease, vicarious menstruation, excessive exertion, psychogenic, psychogenic purpura, and unknown cause.[5] Acute fear and intense mental contemplation are the most frequent causes, as reported in six cases in men condemned to execution, a case occurring during the London blitz, a case involving fear of being raped, a case of fear of a storm while sailing, etc.[6] In our case, the probable cause for hematohidrosis was chronic stress, as the other causes were ruled out by detailed investigations. Hysterical mechanisms and psychosomatic disorders are also believed to induce bleeding.[6] Psychogenic purpura is supposed to be caused by hypersensitivity to the patients' own blood or autoerythrocyte sensitization and is characterized by repeated crops of ecchymoses, gastrointestinal bleedings, and hematuria.  Jhn 19:30 When Jesus therefore had received the vinegar, he said, It isfinished: and he bowed his head, and gave up the ghost. because Jesus went to the limit of His endurance then past the limit of His endurance you and i can be saved
