Thank you so much @jrmichler for the reply.
I totally understand your point of view as in the mass and stiffness matrices we have terms related to kinetic and potential energy. But my point to ask above thing was to find the magnitude and direction of the force for the belt and pulley system on...
The main aim of doing this is, i want to perform modal analysis on the shaft of the fan, and i want to also include the resultant force and the moment acting on the shaft of the fan due to the motion on the pulley. I will attach the formulas that i found and also system image. Can you guys...
