Physic: Help with solving roller support
Click For Summary
Discussion Overview
The discussion revolves around solving a problem related to roller supports in structural mechanics. Participants seek to understand the methodology behind arriving at a specific answer for a loading scenario, which involves distributed loads. The scope includes conceptual clarification and mathematical reasoning related to statics.
Discussion Character
- Exploratory
- Technical explanation
- Homework-related
- Mathematical reasoning
Main Points Raised
- One participant expresses a need for a detailed explanation of how to solve a roller support question, despite having the final answer.
- Another participant requests the original poster to share their work to facilitate assistance and notes the low resolution of the provided figure.
- A participant mentions that the answer is found in a review booklet for an EIT exam, which lacks an explanation for the solution.
- One suggestion involves splitting the loading into two components: a uniformly distributed load and a triangularly distributed load, and determining reactions for each case.
- Another participant echoes the previous suggestion, advising to convert the distributed loads into point loads at their geometric centers to simplify the analysis.
Areas of Agreement / Disagreement
Participants generally agree on the need to break down the problem into simpler components for analysis, but there is no consensus on the specific approach or methodology to be used.
Contextual Notes
The discussion highlights the importance of visual aids in problem-solving, as the low-resolution figure may hinder understanding. Additionally, the lack of detailed steps in the original source material contributes to the uncertainty in the solution process.
Who May Find This Useful
Students and practitioners in engineering and physics who are dealing with problems related to roller supports and distributed loads may find this discussion beneficial.

First, you need to show us your work in order for us to help you. Second, the figure is a bit low-resolution. Can you post a higher-resolution copy?

You should show some attempt at your work. You should consider splitting the loading into two pieces: a uniformly distributed load of 100N/m, and a triangularly distributed load varying from 0 to 100N/m. Determine the reactions for each case and superimpose the results.

Along the lines of what PhantomJay mentioned, you should break this down into two problems...The first has a distributed load of 100 N/m and the other has the varying distributed load. Take both distributed loads and convert them to a point load at the geometric center. Then you have a single load in each. Then it's statics as usual.
