It's whatever the designers make them. It means that for an elevator for instance that the cables can take a much higher load than the elevator is rated for before the cables will snap. If the cables can take double the rated load then the elevator is said to have a safety factor of two.

What is the relation between yield stress and allowable stress?
A factor of safety against yield is applied to design stress Yield Stress/ Design Stress = Factor of safety The factor of safety varies for different industries; 1.5 is used in structural steel design for buildings; 1.25 or even 1.1 for aircraft/space systems
What is difference between partial factor of safety and factor of safety?
A safety factor is an aspect of design that increases strength or protection beyond that suggested as needed by calculation or other basic assessment. For example, engineering calculations might suggest a bridge needs a certain amount of strength in a support beam. That number would be increased by, perhaps, 20% as a "safety factor" in case it were to be stressed beyond its design or in case some basis for the calculation was in error.A partial safety factor is one of several safety factors applied to the same instance.
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.
What are the Advantages and disadvantages of working stress design and ultimate strength design?
Ultimate strength design assumes the entire cross section of a member is subjected to its yield stress and will generally save material, but be less conservative given the same factor of safety.
Is factor of safety of brittle material half of ductile material?
is factor of safety of brittle material half of ductile material
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 safety factor?
Factor of safety is a figure used in structural and geotechnical design applications that provides a design margin over the theoretical design capacity.
What is factor of safety?
Factor of safety is a figure used in structural and geotechnical design applications that provides a design margin over the theoretical design capacity.
How factor of safety is determined in the design?
factor of safety are usually determined from the past statistics of the working element.
How factor of safety is determined in design?
Simply put, if a building needs 4 pillars to stay up and theirs a risk one might get knocked over, design in 6. You then have a safety factor.

What has the author D I Blockley written?

You want at least 4 difference between limit state and working stress method of design?
factor of safety
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 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.
What is a conservative design?
A conservative design is a design within which the designer pays more attention to the loads and other predictable problems and hence he/she takes more preventive decisions just like to take a bigger design factor of safety (F.S.).
