The physical properties of plastic materials are a vital part of product design and quality control. As a result of this, numerous materials tests are carried out. The most rudimentary of these tests ...

A strain gauge is used to measure the strain on an object. It is a very thin, flat coil of conductive wire. (Editor's note: strain “gauge” is often spelled as “gage”; why this is so, and which is ...

Strain—the response of a material to an applied stress due to an applied force or weight—is an important physical parameter in any application ranging from bridge monitoring to IC die packaging and ...

Sooner or later, we’ve all got to deal with torque measurement. Most of us will never need to go beyond the satisfying click of a micrometer-style torque wrench or the grating buzz of a cordless drill ...

An improved strain-gauge dendrometer was tested on apple (Pyrus malus L.) tree trunks and fruit to measure thickness dynamics. The sensor is similar to previous devices, but is more flexible allowing ...
