main advantages to be gained from assembling a system - you are able to determine whether two parts overlap or interfere with each other interference - The amount of overlap between two instances in an assembly clearances - The minimum distances between two instances in an assembly For some systems - you may choose to perform a kinematic analysis of the parts in the assembly to see interference Times to check for interference - n= amount of parts (n-1)! Only one of the two, interference ...

Includes two homework problems that go through the analysis of systems of springs using the Stiffness/Displacement Method. The work goes through how to obtain the global stiffness matrix, full and reduced matrix equations, nodal displacements, and reaction forces.

Lecture notes introducing the Stiffness (Displacement) method for analyzing systems of springs. It goes through concepts like element and global stiffness relations, stiffness matrices, node element connectivity charts, etc.

This document is the finite element method for the combination of linear springs. It shows the way how to calculate the global stiffness matrix using the direct stiffness method and principles of minimum potential energy, nodal displacements, reactions at the support, the forces in each element, and the strain energy in each element. It includes five(5) worked examples of the combination of springs.
