Discover what is strain, its types, its relationship with stress, and a simple guide to calculate it for higher efficiency, improved measurement, and analysis.
Hooke's law is very easy to work with – a luxury not often bestowed on physics work. It says that the force an elastic object exerts against deformation increases proportionally to the displacement of the spring (or elastic object) from its equilibrium position. Using less scientific jargon, ...
When stress is transferred from the load cell flexure to the strain gauge, the resulting deformation or displacement of its material causes strain that ultimately is converted into the load cell’s measurable output. For example, when the film is pulled, it — and the conductors — stretches ...
Stress-strain curves are generated by a tensile testing machine. A specimen usually with a dog bone shape is mounted in the device and an increasing tensile load is applied. The stress is measured as the load divided by the cross-sectional area of the narrowest part of the dog bone. The...
How to calculate ductility from a stress-strain curve? What is the equation for angular momentum? In the product vec{F} = q vec{v} cross vec{B}, take q=3, vec{v} = 2.0 hat{i} + 4.0 hat{j} + 6.0 hat{k} and vec{F} = 30.0 hat{i} - 60.0 hat{j} + 30.0 hat{k}. What...
The way of evaluating this order is to perform a local analysis of the strain energy of the assembly, once the displacement field is parametrized in terms of a suitable parameter. By means of a finite element technique, this analysis can be easily performed through the numerical approach ...
A load cell or strain gauge device is essentially a mechanical support member or bracket equipped with one or more sensors that detect small distortions in the support member. As the force on the load cell changes, the bracket flexes slightly, causing output signal changes. Calibrated load cells...
In some applications, the torque measurement taken with an in-line rotary sensor may be measured at the point where the torque is transferred to the ground using a reaction torque transducer (static torque measurement). A reaction torsion sensor (not LVDT displacement sensors) has two mounting fl...
Lightweight quality:Air-powered tools are lighter than many electric counterparts. Workers can use the tools with minimal strain while maintaining efficiency. Durability:You can use compressed air tools in many heavy-duty applications, from steel mills to construction sites. They can withstand high te...
It is possible to calculate the expected average fragment size for a given genomic DNA if the percent GC content of the DNA and the recognition sequence of the restriction enzyme are known. For example, in a genome with 50% GC content and no dinucleotide bias, a four-cutter can be expecte...
