# How do you calculate beam stiffness?

## How do you calculate beam stiffness?

Its stiffness is S = F/δ, where F is the total load and δ is the bending deflection. Figure 5.7 (c) A beam of square section, loaded in bending. Its stiffness is S = F/δ, where F is the load and δ is the bending deflection.

## What is fixed guided beam?

A fixed-guided beam is one of most commonly used flexible segments in compliant mechanisms such as bistable mechanisms, compliant parallelogram mechanisms, compound compliant parallelogram mechanisms and thermomechanical in-plane microactuators.

Which is the correct equation for beam stiffness?
