Leaner should have to solve same Problem by Using Comsol Multiphysics Software and Use this Knowledge to Practical , Application oriented Problem

This simulation demonstrates how to set up a simple static structural analysis. The analysis is exemplified on a combination wrench during the application of torque on a bolt. Despite its simplicity, and the fact that very few engineers would run a structural analysis before trying to turn a bolt, the example provides an excellent overview of structural analysis in COMSOL Multiphysics.

In this tutorial example, which demonstrates a more generally applicable method, a

structural mechanics model of a spring is augmented by a global equation that solves for

the load required to achieve a desired total extension of the spring.

The stresses in a pulley connected to an engine that drives another pulley are studied in this model.

A parametric analysis is conducted in order to study how the rotational speed affects the stress distribution in the pulley. The power at the pulley shaft remains constant, the moment (defined by the ratio of the power by the rotational speed) will thus decrease with increased speed. This means that with increased rotational speed the inertial load increases and at the same time the driving belt-force decreases.
