Pressure, load, weight density and stress are all names commonly used for distributed loads. Distributed load is a force per unit length or force per unit area depicted with a series of force vectors joined together at the top, and will be designated as \(w(x)\) to indicate that the distributed loading is a function of \(x\text{.}\)

Distributed loads are a way to represent a force over a certain distance. Sometimes called intensity, given the variable: Intensity w = F / d [=] N/m, lb/ft While pressure is force over area (for 3d problems), intensity is force over distance (for 2d problems). It’s like a bunch of mattresses on the back of a truck. You can model it as 1 force acti...
Distributed loads can be modeled as a single point force that is located at the centroid of the object. You can use straight-forward algebra, or use integration for more complex shapes. Then you replace the distributed load with the single point load acting at x distance. See in the truck example: There are two ways to calculate this, using integra...
When there is a complicated shape, it can be easier to model it as more than 1 type of distributed load. You calculate each force separately and then use a weighted equation to find the total distance the force acts from a point that you select.

A non-uniform distributed load refers to a load that is spread over a beam or structural element, but not evenly. This type of load varies in magnitude and can change along the length of the beam, affecting how the beam bends and deflects. Understanding this load type is crucial for analyzing how beams respond to different loading conditions and for designing structures that can withstand such ...
Uniform intensity. A distributed load with a constant intensity over an area is said to have a uniform intensity. Accordingly, a uniform load or a uniformly distributed load conveys the same meaning. With an analogy to the weight load of a box on a surface, the magnitude of total (resultant) force exerted by a uniform load over an area is .
The loading function on such sections is \[ w(x) = C \text{.} \nonumber \] The constant value is negative if the load points down, and positive if it points upward. Uniformly Varying Load. In this case the loading function varies linearly, and will produce a triangular or trapezoidal shear function. The loading function is a straight line.

Jan 14, 2024 · Definition – Uniformly Distributed Load (UDL) A uniformly distributed load (UDL) is an action (load) on a structural element such as a beam, slab or column which has the same value at any point. In general, there are . uniformly distributed line loads and; uniformly distributed area loads; Examples of this load would be snow, wind, live or ...
