- A uniformly distributed load can be represented mathematically as a constant value per unit length, typically denoted as 'w' in equations. The total load from a UDL acting over a beam can be calculated by multiplying the load intensity by the length over which it acts.

Similarly, for a triangular distributed load — also called a uniformly varying load— the magnitude of the equivalent force is the area of the triangle, \(bh/2\) and the line of action passes through the centroid of the triangle.

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.

Uniformly Varying Load. Find the equivalent point force and its point of application for the distributed load shown. Answer. The equivalent load is \(\lb{30}\) downward force acting \(\ft{4}\) from the left end. Solution 1. The equivalent load is the ‘area’ under the triangular load intensity curve and it acts straight down at the centroid ...
A uniformly varying load is also called the triangular load which starts with zero intensity at one end of the beam and varies linearly to the other end of the beam. This variation of load comes under the nonuniform distribution of loads over the beam.
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 .
