Force Calculation in Mechanical Structures

This case study demonstrates how Ascoos OS can be used for technical computations in engineering applications. It calculates force using Newton?s Second Law, stores the result in a JSON file, and logs system events.

Purpose

This example highlights the use of the following Ascoos OS components: - TMathsHandler: Performs force calculations using mathematical operations. - TFilesHandler: Stores results and checks quota limits. - TEventHandler: Logs force calculation events. - TCoreSystemHandler: Monitors CPU load and logs system status.

Structure

The case study is implemented in a single PHP file: - engineering_forces.php: Includes calculation, storage, and logging.

Prerequisites

1. Ensure Ascoos OS is installed (main repository).
2. Write permissions for `$AOS_LOGS_PATH` and `$AOS_TMP_DATA_PATH/ascoos_data/engineering/`.
3. Global variables (`$conf`, `$AOS_TMP_DATA_PATH`, `$AOS_LOGS_PATH`) are automatically set by Ascoos OS.
4. The phpBCL8 library is preinstalled and auto-loaded.

Getting Started

1. Run the script via a web server:
   https://localhost/aos/examples/case-studies/engineering/forces/engineering_forces.php
   

Example Usage

$mass = 100.0; // kg
$acceleration = 9.81; // m/s^2
$force = $maths->power($mass $acceleration, 1); // F = m a

Expected Output

The script generates a JSON file with the calculated force. Example output:

{
  "structure_id": "STR001",
  "force": 981,
  "timestamp": "2025-08-18T15:21:00+03:00"
}
