How do you measure strain with a strain gage?
Instrumentation and Data Acquisition is one of those “gray area” subjects.
It’s not all out Electrical theory or Material Science, but is out there enough to scare many of us – but it can easily become a subject you are looking forward to working on the exam once you are exposed to some of the basic theories within.
In this video, we jump in to a problem that is covered within the subject of INSTRUMENTATION & DATA ACQUISITION, specifically walking you through measuring strain using a strain gage.
This is a collegiate themed scenario for all of you Gator fans, so enjoy.
Key Definition
What is a STRAIN GAGE?
A STRAIN GAGE, which you may also see spelled as STRAIN GAUGE, is a sensor whose resistance varies with applied force.
A STRAIN GAGE converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured.
When external forces are applied to a stationary object, stress and strain are the result.
Stress is defined as the object’s internal resisting forces, and strain is defined as the displacement and deformation that occur.
Check out the video and see how we can go about solving this type of problem in the most efficient manner.
