The Influence of Sealant Modulus on the Bending Stiffness of Multilayer Films (.pdf)
. The model was validated by comparing the calculated stiffness. factor to experimental measurements of bending stiffness. The stiffness test involves pushing a film into a. narrow slot, as shown in Figure 4. The force to push the film into the slot is measured as a function of. displacement...

Shaft Displacement Measurement Using A PROTOR System
, misalignment, rotor bends, cracks and so on. Figure 2 : Bending of rotor shaft. For example, assume a rotor, supported by two bearings, has a bend or bow as shown in Figure 2 (greatly exaggerated for display purposes). Measuring the shaft displacement at the bearing would show a sinusoidal-type waveform...
Synchronized versus Sequential Sampling Methods (Multiplexing) for Measurement Systems

Torque Measurement Primer (.pdf)
and radio telemetry. A torque transducer, like a load cell, consists of a metal spring element, or flexure. Strain gages are applied to the flexure in a Wheatstone bridge configuration. Torque applied to the sensor causes bending or shear strain in the gaged area, generating an output voltage signal...
