A flexure pivot, utilized in place of bearings for their frictionless properties in precision alignment mechanisms and scientific instruments. A flexure bearing is a category of flexure which is engineered to be compliant in one or more angular degrees of freedom. Flexure bearings are often part of compliant mechanisms. Flexure bearings serve ...
A flexure pivot, utilized in place of bearings for its frictionless adjustment properties. A living hinge (a type of flexure), on the lid of a Tic Tac box. This hinge has one compliant degree of freedom. A flexure is a flexible element (or combination of elements) engineered to be compliant in specific degrees of freedom. [1]
A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
[citation needed] Other optimization techniques focus topology optimization of the flexure joints by taking as input a rigid mechanism and replacing all the rigid joints with optimized flexure joints. [4] To predict the behavior of the structure, finite-element stress analysis is done to find deformation and stresses over the entire structure.
FACT library of freedom and constraint spaces used to design parallel flexure systems. Freedom and constraint topologies (a.k.a., freedom, actuation, and constraint topologies; or simply FACT) [1] [2] [3] is a mechanical design framework developed by Dr. Jonathan B. Hopkins.
Also, this linear distribution is only applicable if the maximum stress is less than the yield stress of the material. For stresses that exceed yield, refer to article plastic bending. At yield, the maximum stress experienced in the section (at the furthest points from the neutral axis of the beam) is defined as the flexural strength.

Zaber motorized linear stage. A linear stage or translation stage is a component of a precise motion system used to restrict an object to a single axis of motion. The term linear slide is often used interchangeably with "linear stage", though technically "linear slide" refers to a linear motion bearing, which is only a component of a linear stage.
