        abstract = {A Bell Crank Lever is a bar that rotates about a fixed point, commonly used in railway signaling, Hartnell-type governors, and air pump drives in condensers. It functions to lift loads with minimal effort while altering motion through angles, typically 90° or 180°. The primary stresses in the lever are bending stress at the fulcrum and shear stress on the fulcrum pin, with maximum stress concentration at the fulcrum. This study focuses on the stress analysis of the Bell Crank Lever within an angle range of 90° to 180°, employing the Finite Element Method (FEM) using ANSYS Workbench 14.5 and photoelasticity as an experimental validation technique. The experimental analysis utilizes photoelastic sheets of Araldite with hardener HY-951 and curing agent CY-230. A comparison of analytical and experimental results demonstrates close agreement, confirming the accuracy of the stress analysis.},
