What has the author E A Higgins written?
E. A Higgins has written: 'Three reports relevant to stress in aviation personnel' -- subject(s): Stress (Physiology), Air traffic controllers
What is working stress method?
it is a method of design in rcc structures, in which stresses of materials is calculated by using working load and compared with allowable stress by considering a linear stress strain relation ship.
What is the suicide rate for air traffic controllers?
There has not been a significant report on suicidal deaths of air traffic controllers. Though they are in a very high responsibility, high stress job, they are professionals and it appears their suicide rates are actually very low.
Do police officers have stress involved in this job?
according to a recent study, air controllers have the most stressful job, police are a close second
Which method is good limit state method or working stress method?
The methods depend based on the type of structures. for eg. for water Retaining structures the Working stress method gives good life and for other structures which is not exposed to water, mostly limit state design works.
What is the formula for j in working stress method?
1-(k/3)
Which is economical design out of Limit state and working stress?
limit state method
Why does stress balls relieve stress?
Because they get your mind on something else besides what your stressing about kind of like the counting to ten method when your angry.
What is the difference between proportional limit and yield strength?
Proportional limit is the maximum stress for which strain remains proportional to stress. As it is usually not obvious, industry accept to use offset method 0.0001 in/in. Yield stress is stress level which detrimental damage is assumed to occur (plasticity). This point is also not exhibited well in certain metal, so industry accept to use offset method 0.002 in/in.
What method for stress testing would provide the most predictable work load?
Bicycle ergometer
What is Working stress method of RCC design?
This is the method in which the structure is analyzed by elastic theory i.e. theory of simple bending in which materials obey the Hook's law.
Why use working stress method for water tank design?
i think , because water tanks are more vulnerable structures and plus the tank is sometime overfilled and sometime empty, the pressure inside is so varying, its needs more safety precautions and as we all know working stress method assumes more safety factor than limit state design, which is an economical design, we prefer to use working stress method...
