How factor of safety is determined in the design?
factor of safety are usually determined from the past statistics of the working element.
What would happen if the contianer did not have pressure relese valve?
As the pressure increased, eventually the container would burst. Before such a dangerous pressure is reached, a safety valve would open and automatically release the pressure, preventing the container from bursting. An example is the safety valve fitted to the lid of a domestic pressure cooker used in the kitchen. When the safety valve opened, steam would be released and warn the cook to turn heat on the kitchen stove down to a safer level.
What is a bursting disc?
A bursting disc is the same as a blown disc or a ruptured disc. It happens after the disc starts to create a bulge, showing a sign of weakness under the pressure of keeping the vertebrae above and below it separated and finally bursts under the pressure. A small disk inside of a screw that is inserted into the side of a CO2 or compressed air tank. If the air pressure inside the tank exceeds a certain pressure, the burst disk will blow out, releasing all the pressure inside the tank. This safety device keeps over-filled tanks from exploding. Also called a safety disc.
How do you calculate safe working load of a ship's bollard?
SWL = Ultimate (Breaking) Strength/Design (Safety) Factor Usually the safety factor used in lifting equipment is 5:1. Example: If you are using a 0.5" Improved Plow Wire Rope the ultimate strength is 11.5 tons. SWL = 11.5/5 = 2.3 tons The safety factor should go higher if there is possibility of injury or death. Example: Elevators use a 20:1 safety factor.
What is the difference between factor of safety and safety factor?
There is no difference between "factor of safety" and "safety factor." They are two ways of saying the same thing.
What do you mean by partial safety factor?
The factor of safety for loads is known as partial safety factor. Partial safety factor=Design load/Characteristicload
What is factor of safety in Crane load lifting?
If SLI is in operating condition then sLI itself will indicates that whether load is in safe mode. But if SLI is not working then one must be considered 40 % factor of safety of crane SWL and in SLI working condition it will be considered 20 % of its SWL.
You want at least 4 difference between limit state and working stress method of design?
factor of safety
What is the difference between a safety factor and a factor of safety?
Both are meaning the same definition. simply you put factor beyond the safety.
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...
How is boiler spring loaded safety valve works?
when the pressure increases over the maximum allowable working pressure of the vessel, the valve will open to protect against overpressure.
What is the factor of safety value for working stress method?
for concrete a F.O.S. upto 3 is used . and for steel 1.75 to 1.85 .. is used.
