The term stress (s) is used to express the loading in terms of force applied to a certain cross-sectional area of an object. From the perspective of loading, stress is the applied force or system of forces that tends to deform a body. From the perspective of what is happening within a material, stress is the internal distribution of forces within a body that balance and react to the loads applied to it. The stress distribution may or may not be uniform, depending on the nature of the loading condition.
The video on the left shows a typical spiral elevator designed by VPC-Systems.
As you can see by the analysis and due to the design characteristics of our spirals the overall stress on the materials is very low ( all blue), this indicates ideal performance and most importantly reliability within the structure.
