Mechanics - factored self weight of an object

In summary, the conversation discusses how to find the factored self weight of an object by using the dimensions and mass per metre. It is suggested to first find the unit weight by multiplying the mass per metre by 9.81 m/s^2, and then possibly multiplying it by a factor such as 1.4 to obtain the factored self weight. There is also a mention of the density function and a question about the difference between UDL and self-weight.

Mechanics -- factored self weight of an object

How would you find the factored self weight of an object, suppose you are given the the dimensions and mass per metre of the object. Would you find the unit weight first by multiply by 9.81 and then multiplying the volume to find the UDL?

leagcy21: If you are given mass per metre, then just multiply mass per metre by 9.81 m/s^2, to obtain the UDL.

Then, to make the UDL a factored self weight, you probably would multiply the UDL by something like 1.4.

Welcome to PF;
we'd expect to be given the density function - it's not clear what "mass per meter".
Per your question: try it both ways for a handy example - do you get a different answer?

I thought UDL was different from self-weight?
 

1. What is the "factored self weight" of an object?

The factored self weight of an object refers to the total weight of the object, including its own weight and any additional loads or forces that are acting on it. This is an important concept in mechanics because it helps to determine the overall stability and structural integrity of an object.

2. How is the factored self weight calculated?

The factored self weight is calculated by multiplying the object's actual weight by a factor that takes into account any additional loads or forces acting on the object. This factor is typically determined by engineers or scientists who are designing the object and is based on factors such as safety margins and expected usage conditions.

3. Why is it important to consider the factored self weight of an object?

Considering the factored self weight of an object is important because it helps to ensure the object is structurally sound and can withstand the loads and forces it will be subjected to. Neglecting to factor in the self weight could result in a design that is not strong enough to support itself and any additional loads, leading to potential safety hazards.

4. How does the factored self weight affect the overall stability of an object?

The factored self weight has a significant impact on the stability of an object. If the object is not able to support its own weight, it may collapse or fail under additional loads. Additionally, the factored self weight can affect the center of gravity of an object, which can also impact its stability.

5. Can the factored self weight of an object change?

Yes, the factored self weight of an object can change depending on various factors such as the addition or removal of components, changes in usage conditions, or modifications to the design. It is important to regularly reassess and recalculate the factored self weight to ensure the object remains structurally sound.
